Abstract—Fourth generation wireless communication system is expected to support high data rate multimedia services which is possible through Wideband Code Division Multiple Access (WCDMA) systems. Multi carrier CDMA system provides the advantage of frequency diversity and processing gain 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 and interference suppression. Error performance and capacity of OFDM based system can be improved through proper synchronization. In this paper, virtual sub carrier based frequency and phase synchronization algorithm is proposed which reduces the BER of MC CDMA systems indeed without any transmission overhead.
Index Terms—Synchronization, MC CDMA, OFDM, Biterror rate, Capacity.
