Comparison between MC-CDMA and CDMA-OFDM/OQAM systems

mc-cdma system is susceptible to phase noise and carrier frequency offset (cfo) which leads to loss of orthogonality among the subcarriers causes an undesired effect called ici that degrades the system performance [2, 3].-carrier code division multiple access (mc-cdma) technique is one of the strong candidates for next generation wireless mobile communication systems.

Blind multiuser detection for asynchronous MC-CDMA systems

Hybrid ARQ schemes for future wireless systems based on MC-CDMA

mc-cdma signal which is the inverse fft (ifft) of cdma signal is given by. the cir performance of cc technique is inferior to normal mc-cdma system in high frequency offset conditions.
