Abstract :
In third generation wireless communication system, high data rate multimedia services are achieved through wideband code division multiple access (W-CDMA) systems. Multi carrier CDMA system provides the advantage of frequency diversity in CDMA system and thus reduces the bit error rate. Capacity of CDMA based systems can be increased by decreasing BER, which is possible through interference reduction, interference cancellation and proper synchronization. In this paper, virtual sub carrier based frequency synchronization algorithm is proposed which reduces the BER of MC CDMA system without any transmission overhead and hence enhances the capacity
