The antenna was calculated to operate in 3.1–10.6 GHz ultra-wideband frequency band, even though the measurements revealed that it covers the band 3.4–12 GHz. It&#39;s manufactured on the basis of Rogers RO4350B, which is appropriate for this band. Antenna&#39;s total size with SMA connector 72970 Pomona is 39 mm × 19 mm. The main goal stated in this paper is to prove the antenna&#39;s characteristics, simulated before, by carrying out full-time measurements in anechoic chamber.

The detail description of the current state of research in this field is presented and deeply analyzed, so finally the new unique solutions are proposed and described in detail.Since the transceiver antenna has a significant effect on the signal shape working as a spatio-temporal filter, then the phase of the emitted wave (spin-orbital state) depends only on the antenna geometry. So the inverse problem of the antenna theory should be solved, when the antenna array configuration is synthesized on the basis of the given aperture.The antenna is considered as distributed in-space volume antenna arraybased on tripoles, providing the reception of a «tangled» signal with wave division and spin-orbital state multiplexing. The antenna is calculated using a mathematical and computer modelling and characterized with stable characteristics in the ultra-wide frequency band.","publication_name":"Journal of Physics: Conference Series","grobid_abstract_attachment_id":80047723},"translated_abstract":null,"internal_url":"https://www.academia.edu/70207348/Ultra_wideband_vortex_antenna_array_design_for_high_capacity_radio_links","translated_internal_url":"","created_at":"2022-02-01T02:50:13.214-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":213594000,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":80047723,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/80047723/thumbnails/1.jpg","file_name":"pdf.pdf","download_url":"https://www.academia.edu/attachments/80047723/download_file?st=MTczMjk2MjMzMyw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Ultra_wideband_vortex_antenna_array_desi.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/80047723/pdf-libre.pdf?1643712911=\u0026response-content-disposition=attachment%3B+filename%3DUltra_wideband_vortex_antenna_array_desi.pdf\u0026Expires=1732965933\u0026Signature=ckRxwqRrsI5X2JRkOAw2xYNtJio5zDf-6ASFBTktiL-eoCzmXDvtQc7RyonuocjJpm5t2tZ~ni3LY-WqKTI~y3CI0hrTVzDMa4YPEC3HFSQfuDtPgYL6wEAKl7u66DHpzmbXegpffQneyjrSfHtIH5l0-lXTGaP5k8GA8I-kOJvloxpmDGzXCsaOzxPHaILKjgS0Y1U1qUPfB21bW0BZUI6L9Lgnsfsh6XMIzXbARrS7aqX0OYnY5wOyTXnQ6IBvwk9jMgItdX2ykyndfk0pwPLCfiRRhKWdXvOVXXe4b83DgAS9UrjDYxogF6vefSnnVAzkdMklZPEfmd6doNp0hQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Ultra_wideband_vortex_antenna_array_design_for_high_capacity_radio_links","translated_slug":"","page_count":10,"language":"en","content_type":"Work","owner":{"id":213594000,"first_name":"Ivan","middle_initials":null,"last_name":"Meshkov","page_name":"MeshkovI","domain_name":"independent","created_at":"2022-02-01T02:48:52.980-08:00","display_name":"Ivan Meshkov","url":"https://independent.academia.edu/MeshkovI"},"attachments":[{"id":80047723,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/80047723/thumbnails/1.jpg","file_name":"pdf.pdf","download_url":"https://www.academia.edu/attachments/80047723/download_file?st=MTczMjk2MjMzMyw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Ultra_wideband_vortex_antenna_array_desi.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/80047723/pdf-libre.pdf?1643712911=\u0026response-content-disposition=attachment%3B+filename%3DUltra_wideband_vortex_antenna_array_desi.pdf\u0026Expires=1732965933\u0026Signature=ckRxwqRrsI5X2JRkOAw2xYNtJio5zDf-6ASFBTktiL-eoCzmXDvtQc7RyonuocjJpm5t2tZ~ni3LY-WqKTI~y3CI0hrTVzDMa4YPEC3HFSQfuDtPgYL6wEAKl7u66DHpzmbXegpffQneyjrSfHtIH5l0-lXTGaP5k8GA8I-kOJvloxpmDGzXCsaOzxPHaILKjgS0Y1U1qUPfB21bW0BZUI6L9Lgnsfsh6XMIzXbARrS7aqX0OYnY5wOyTXnQ6IBvwk9jMgItdX2ykyndfk0pwPLCfiRRhKWdXvOVXXe4b83DgAS9UrjDYxogF6vefSnnVAzkdMklZPEfmd6doNp0hQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"},{"id":80047722,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/80047722/thumbnails/1.jpg","file_name":"pdf.pdf","download_url":"https://www.academia.edu/attachments/80047722/download_file","bulk_download_file_name":"Ultra_wideband_vortex_antenna_array_desi.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/80047722/pdf-libre.pdf?1643712910=\u0026response-content-disposition=attachment%3B+filename%3DUltra_wideband_vortex_antenna_array_desi.pdf\u0026Expires=1732965933\u0026Signature=gipca9WiDYG8VuM-HlUwVwD3BpWQmr9~Fs9uZRglB7HfA~-MTUh2XOOgJaGOVeYT5z5rr2UZ3BuQ7wS5gpL0A0BPS69hbPnIc4-buBIcCwT~zdFRJypyPuN96EY4uvQVCaFGVJJ0JL3gTNuxGapdZ8P43NL2IT4eLJSvrVXQb2gZl1XxJ5ySsIqoqu2r6f9Sq1kpBzWcmjM2XyrkOWkWC6CrRhyx1kiutyM5ocYuwG~XB~AQzmpI0hyCnRNu6YaWUcKUUxi-Sblakh81jKRN0kEd49w8PkwesSarYOoDmbaqVMw-voX8YvZUAX4PmJQWv8gEKeTVVPT84BEksFK2dg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":48,"name":"Engineering","url":"https://www.academia.edu/Documents/in/Engineering"},{"id":118582,"name":"Physical sciences","url":"https://www.academia.edu/Documents/in/Physical_sciences"}],"urls":[{"id":17183888,"url":"http://stacks.iop.org/1742-6596/1096/i=1/a=012164/pdf"}]}, dispatcherData: dispatcherData });

Finally we introduce preliminary results for system performance with expanded number of applied pulses and advanced symbol coding technique.","internal_url":"https://www.academia.edu/70207376/Spectral_Modulation_Technique_Based_on_Frequency_Shift_Keying_for_High_Speed_Optical_Fiber_Wireless_Communication_System","translated_internal_url":"","created_at":"2022-02-01T02:50:15.056-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":213594000,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[],"slug":"Spectral_Modulation_Technique_Based_on_Frequency_Shift_Keying_for_High_Speed_Optical_Fiber_Wireless_Communication_System","translated_slug":"","page_count":null,"language":"en","content_type":"Work","owner":{"id":213594000,"first_name":"Ivan","middle_initials":null,"last_name":"Meshkov","page_name":"MeshkovI","domain_name":"independent","created_at":"2022-02-01T02:48:52.980-08:00","display_name":"Ivan Meshkov","url":"https://independent.academia.edu/MeshkovI"},"attachments":[],"research_interests":[{"id":422,"name":"Computer Science","url":"https://www.academia.edu/Documents/in/Computer_Science"}],"urls":[{"id":17183895,"url":"http://xplorestaging.ieee.org/ielx7/8585254/8602430/08602869.pdf?arnumber=8602869"}]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="70207375"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/70207375/The_Propagation_Model_of_Modulated_Subterahertz_Signals_in_the_RoF_Communication_Systems"><img alt="Research paper thumbnail of The Propagation Model of Modulated Subterahertz Signals in the RoF Communication Systems" class="work-thumbnail" src="https://a.academia-assets.com/images/blank-paper.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/70207375/The_Propagation_Model_of_Modulated_Subterahertz_Signals_in_the_RoF_Communication_Systems">The Propagation Model of Modulated Subterahertz Signals in the RoF Communication Systems</a></div><div class="wp-workCard_item"><span>2018 International Multi-Conference on Industrial Engineering and Modern Technologies (FarEastCon)</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">Radio-over-Fiber system scheme is described in the paper, the radio domain of this system is perf...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">Radio-over-Fiber system scheme is described in the paper, the radio domain of this system is performed in the range 75–110 GHz (W-band).

The measurement scheme is based on the use of a wellknown experimental setup designed to obtain the profile of the refractive index of an optical fiber.

The experimental study confirms the simulation results, providing the 6.5 dB peak-to-average power ratio decrease for Discrete Fourier Transform function.","publisher":"IEEE","publication_name":"2019 International Conference on Electrotechnical Complexes and Systems (ICOECS)"},"translated_abstract":"In this paper we present the Peak-to-Average Power Ratio decrease method targeted at energy efficiency improvement of the Radio-over-fiber telecommunication systems based on the Orthogonal Frequency Division Multiplexing.

It is also proposed to use chiral fiber-optic periodic structures as sensors of physical fields (temperature, strain, etc.), which can be applied to address multi-sensor monitoring systems due to a unique address parameter—th...","internal_url":"https://www.academia.edu/70207357/Generation_of_Vortex_Optical_Beams_Based_on_Chiral_Fiber_Optic_Periodic_Structures","translated_internal_url":"","created_at":"2022-02-01T02:50:13.753-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":213594000,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":80047787,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/80047787/thumbnails/1.jpg","file_name":"sensors-20-05345.pdf","download_url":"https://www.academia.edu/attachments/80047787/download_file?st=MTczMjk2MjMzMyw4LjIyMi4yMDguMTQ2&st=MTczMjk2MjMzMyw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Generation_of_Vortex_Optical_Beams_Based.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/80047787/sensors-20-05345-libre.pdf?1643712915=\u0026response-content-disposition=attachment%3B+filename%3DGeneration_of_Vortex_Optical_Beams_Based.pdf\u0026Expires=1732965932\u0026Signature=aU8RQg~5lmGw5wooCDkuUeYCwQtg5hzY1FetvVZcMzxfwChUxjCxB5CZqA8SN1i3LhYIcn3moXACGBaaJ5SsxmuxSYx6sjOH96CCXuy3WlQHHN53xYhvbWu~Yf1XBZH-a-hX2~yi~h6h8v6vteTpsuwuurhD8gDuC6d3xh5X9e7Q4ZwkjFjdoGxhqVKEndd0VD5cjawyHJRkVLiNkFLzDlPGiC1xqFxjV9iK7Jzggm6O00XETPzDAe9qWSrigYsSRC~Mau~D8a4zAiAuLmVPTkoWuPippDStODC3ARpRwEH5e-x9scMH718v6yEWWNf9IjGV2k-u5zbn5zSJbt0euA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Generation_of_Vortex_Optical_Beams_Based_on_Chiral_Fiber_Optic_Periodic_Structures","translated_slug":"","page_count":16,"language":"en","content_type":"Work","owner":{"id":213594000,"first_name":"Ivan","middle_initials":null,"last_name":"Meshkov","page_name":"MeshkovI","domain_name":"independent","created_at":"2022-02-01T02:48:52.980-08:00","display_name":"Ivan Meshkov","url":"https://independent.academia.edu/MeshkovI"},"attachments":[{"id":80047787,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/80047787/thumbnails/1.jpg","file_name":"sensors-20-05345.pdf","download_url":"https://www.academia.edu/attachments/80047787/download_file?st=MTczMjk2MjMzMyw4LjIyMi4yMDguMTQ2&st=MTczMjk2MjMzMyw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Generation_of_Vortex_Optical_Beams_Based.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/80047787/sensors-20-05345-libre.pdf?1643712915=\u0026response-content-disposition=attachment%3B+filename%3DGeneration_of_Vortex_Optical_Beams_Based.pdf\u0026Expires=1732965932\u0026Signature=aU8RQg~5lmGw5wooCDkuUeYCwQtg5hzY1FetvVZcMzxfwChUxjCxB5CZqA8SN1i3LhYIcn3moXACGBaaJ5SsxmuxSYx6sjOH96CCXuy3WlQHHN53xYhvbWu~Yf1XBZH-a-hX2~yi~h6h8v6vteTpsuwuurhD8gDuC6d3xh5X9e7Q4ZwkjFjdoGxhqVKEndd0VD5cjawyHJRkVLiNkFLzDlPGiC1xqFxjV9iK7Jzggm6O00XETPzDAe9qWSrigYsSRC~Mau~D8a4zAiAuLmVPTkoWuPippDStODC3ARpRwEH5e-x9scMH718v6yEWWNf9IjGV2k-u5zbn5zSJbt0euA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[],"urls":[{"id":17183889,"url":"https://www.wikidata.org/entity/Q99605227"}]}, dispatcherData: dispatcherData });

The detail description of the current state of research in this field is presented and deeply analyzed, so finally the new unique solutions are proposed and described in detail.Since the transceiver antenna has a significant effect on the signal shape working as a spatio-temporal filter, then the phase of the emitted wave (spin-orbital state) depends only on the antenna geometry. So the inverse problem of the antenna theory should be solved, when the antenna array configuration is synthesized on the basis of the given aperture.The antenna is considered as distributed in-space volume antenna arraybased on tripoles, providing the reception of a «tangled» signal with wave division and spin-orbital state multiplexing. The antenna is calculated using a mathematical and computer modelling and characterized with stable characteristics in the ultra-wide frequency band.","publication_name":"Journal of Physics: Conference Series","grobid_abstract_attachment_id":80047723},"translated_abstract":null,"internal_url":"https://www.academia.edu/70207348/Ultra_wideband_vortex_antenna_array_design_for_high_capacity_radio_links","translated_internal_url":"","created_at":"2022-02-01T02:50:13.214-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":213594000,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":80047723,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/80047723/thumbnails/1.jpg","file_name":"pdf.pdf","download_url":"https://www.academia.edu/attachments/80047723/download_file?st=MTczMjk2MjMzMyw4LjIyMi4yMDguMTQ2&st=MTczMjk2MjMzMyw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Ultra_wideband_vortex_antenna_array_desi.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/80047723/pdf-libre.pdf?1643712911=\u0026response-content-disposition=attachment%3B+filename%3DUltra_wideband_vortex_antenna_array_desi.pdf\u0026Expires=1732965933\u0026Signature=ckRxwqRrsI5X2JRkOAw2xYNtJio5zDf-6ASFBTktiL-eoCzmXDvtQc7RyonuocjJpm5t2tZ~ni3LY-WqKTI~y3CI0hrTVzDMa4YPEC3HFSQfuDtPgYL6wEAKl7u66DHpzmbXegpffQneyjrSfHtIH5l0-lXTGaP5k8GA8I-kOJvloxpmDGzXCsaOzxPHaILKjgS0Y1U1qUPfB21bW0BZUI6L9Lgnsfsh6XMIzXbARrS7aqX0OYnY5wOyTXnQ6IBvwk9jMgItdX2ykyndfk0pwPLCfiRRhKWdXvOVXXe4b83DgAS9UrjDYxogF6vefSnnVAzkdMklZPEfmd6doNp0hQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Ultra_wideband_vortex_antenna_array_design_for_high_capacity_radio_links","translated_slug":"","page_count":10,"language":"en","content_type":"Work","owner":{"id":213594000,"first_name":"Ivan","middle_initials":null,"last_name":"Meshkov","page_name":"MeshkovI","domain_name":"independent","created_at":"2022-02-01T02:48:52.980-08:00","display_name":"Ivan Meshkov","url":"https://independent.academia.edu/MeshkovI"},"attachments":[{"id":80047723,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/80047723/thumbnails/1.jpg","file_name":"pdf.pdf","download_url":"https://www.academia.edu/attachments/80047723/download_file?st=MTczMjk2MjMzMyw4LjIyMi4yMDguMTQ2&st=MTczMjk2MjMzMyw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Ultra_wideband_vortex_antenna_array_desi.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/80047723/pdf-libre.pdf?1643712911=\u0026response-content-disposition=attachment%3B+filename%3DUltra_wideband_vortex_antenna_array_desi.pdf\u0026Expires=1732965933\u0026Signature=ckRxwqRrsI5X2JRkOAw2xYNtJio5zDf-6ASFBTktiL-eoCzmXDvtQc7RyonuocjJpm5t2tZ~ni3LY-WqKTI~y3CI0hrTVzDMa4YPEC3HFSQfuDtPgYL6wEAKl7u66DHpzmbXegpffQneyjrSfHtIH5l0-lXTGaP5k8GA8I-kOJvloxpmDGzXCsaOzxPHaILKjgS0Y1U1qUPfB21bW0BZUI6L9Lgnsfsh6XMIzXbARrS7aqX0OYnY5wOyTXnQ6IBvwk9jMgItdX2ykyndfk0pwPLCfiRRhKWdXvOVXXe4b83DgAS9UrjDYxogF6vefSnnVAzkdMklZPEfmd6doNp0hQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"},{"id":80047722,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/80047722/thumbnails/1.jpg","file_name":"pdf.pdf","download_url":"https://www.academia.edu/attachments/80047722/download_file","bulk_download_file_name":"Ultra_wideband_vortex_antenna_array_desi.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/80047722/pdf-libre.pdf?1643712910=\u0026response-content-disposition=attachment%3B+filename%3DUltra_wideband_vortex_antenna_array_desi.pdf\u0026Expires=1732965933\u0026Signature=gipca9WiDYG8VuM-HlUwVwD3BpWQmr9~Fs9uZRglB7HfA~-MTUh2XOOgJaGOVeYT5z5rr2UZ3BuQ7wS5gpL0A0BPS69hbPnIc4-buBIcCwT~zdFRJypyPuN96EY4uvQVCaFGVJJ0JL3gTNuxGapdZ8P43NL2IT4eLJSvrVXQb2gZl1XxJ5ySsIqoqu2r6f9Sq1kpBzWcmjM2XyrkOWkWC6CrRhyx1kiutyM5ocYuwG~XB~AQzmpI0hyCnRNu6YaWUcKUUxi-Sblakh81jKRN0kEd49w8PkwesSarYOoDmbaqVMw-voX8YvZUAX4PmJQWv8gEKeTVVPT84BEksFK2dg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":48,"name":"Engineering","url":"https://www.academia.edu/Documents/in/Engineering"},{"id":118582,"name":"Physical sciences","url":"https://www.academia.edu/Documents/in/Physical_sciences"}],"urls":[{"id":17183888,"url":"http://stacks.iop.org/1742-6596/1096/i=1/a=012164/pdf"}]}, dispatcherData: dispatcherData });

This paper proposes modeling for two types of devices for optical signal splitting and chirping: the interference-type optical signal splitting and chirping device and the long-distance-type optical signal splitting and chirping device.","internal_url":"https://www.academia.edu/70207346/Optical_signal_splitting_and_chirping_device_modeling","translated_internal_url":"","created_at":"2022-02-01T02:50:13.125-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":213594000,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[],"slug":"Optical_signal_splitting_and_chirping_device_modeling","translated_slug":"","page_count":null,"language":"en","content_type":"Work","owner":{"id":213594000,"first_name":"Ivan","middle_initials":null,"last_name":"Meshkov","page_name":"MeshkovI","domain_name":"independent","created_at":"2022-02-01T02:48:52.980-08:00","display_name":"Ivan Meshkov","url":"https://independent.academia.edu/MeshkovI"},"attachments":[],"research_interests":[],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="70207345"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/70207345/Experimental_demonstration_of_high_speed_data_transmission_based_on_Gaussian_pulses_for_IR_UWB_radio_over_fiber_systems"><img alt="Research paper thumbnail of Experimental demonstration of high-speed data transmission based on Gaussian pulses for IR-UWB radio-over-fiber systems" class="work-thumbnail" src="https://a.academia-assets.com/images/blank-paper.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/70207345/Experimental_demonstration_of_high_speed_data_transmission_based_on_Gaussian_pulses_for_IR_UWB_radio_over_fiber_systems">Experimental demonstration of high-speed data transmission based on Gaussian pulses for IR-UWB radio-over-fiber systems</a></div><div class="wp-workCard_item"><span>Optical Technologies for Telecommunications 2016</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">Experimental bench, which provides high-speed data transmission for IR-UWB Radio-over-Fiber syste...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">Experimental bench, which provides high-speed data transmission for IR-UWB Radio-over-Fiber systems on the basis of Gaussian pulses, is presented in the paper.
