Abstract
In this paper, a modified successive interference cancellation (SIC) scheme is designed for multiuser detection in multicarrier code division multiple access (MC-CDMA) communication systems. Successive interference cancellation (SIC) is used to mitigate the multiple access interference (MAI) which occurs in MC-CDMA systems. SIC uses the decision feedback concept where the signal from a user is regenerated and then subtracted from the received signal to cancel the interference. SIC is a near far resistant system. On the contrary, the problem of latency occurs in the system at each stage of regeneration due to which its practical implementation is not useful. Thus, a modified scheme called dynamic SIC (dSIC) is designed to reduce the latency of the system by half which also gives a lower bit error rate (BER).
