power allocation problems for an uplink user-centric (UC) cell-free massive multiple-input multiple-output (CF-mMIMO) system. Besides, we assume each access point (AP) is connected to a central processing unit (CPU) via fronthaul link with limited capacity. To efficiently use the fronthaul capacity, two strategies for transmitting signals from APs to the CPU are employed; namely: compress-forward-estimate (CFE), estimate-compress-forward (ECF). The capacity of the aforementioned strategies in user-centric CF-mMIMO are drived. Then, we solved the two power allocation problems with minimum Spectral Efficiency (SE) and sum-SE maximization objectives for ECF and CFE strategies. </p> <iframe src="https://publications.waset.org/10013732.pdf" style="width:100%; height:400px;" frameborder="0"></iframe> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Cell-free%20massive%20MIMO" title="Cell-free massive MIMO">Cell-free massive MIMO</a>, <a href="https://publications.waset.org/search?q=limited%20capacity%20fronthaul" title=" limited capacity fronthaul"> limited capacity fronthaul</a>, <a href="https://publications.waset.org/search?q=spectral%20efficiency" title=" spectral efficiency"> spectral efficiency</a>, <a href="https://publications.waset.org/search?q=power%20allocation%20problem." title=" power allocation problem."> power allocation problem.</a> </p> <a href="https://publications.waset.org/10013732/power-allocation-in-user-centric-cell-free-massive-mimo-systems-with-limited-fronthaul-capacity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10013732/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10013732/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10013732/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10013732/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10013732/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10013732/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10013732/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10013732/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10013732/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10013732/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10013732.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">72</span> </span> <p class="card-text"><strong>References:</strong></p> <br>[1] Giovanni Interdonato, Emil Bjornson, Hien Quoc Ngo, PalFrenger, and Erik G Larsson, “Ubiquitous cell-free massive MIMO communications,” EURASIP J.
