The performance\nof the system is shown in the simulated results of the bit error rate\n(BER) and the eye diagram of both systems. The comparison results\nindicate that the Multiple Access Interference (MAI) effects have a\nsignificant impact on SS-WDM over SAC Optical CDMA systems.\nFinally, in terms of spectral efficiency at constant BER of 10-12, SSWDM\noffers higher spectral efficiency than optical CDMA since no\nbandwidth expansion in needed.","references":"[1] Hongxi Yin, David J.
