摘要
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 (HER). Capacity of CDMA based systems can be increased by decreasing BER, which is possible through interference reduction, interference suppression and proper synchronization. In this study, novel frequency and frame synchronization algorithms are proposed which reduces the frame error rate and BER of MC CDMA system without any transmission overhead. Synchronization schemes proposed also help to incorporate variable frame size for each user so that integration of multimedia service is possible. © 2006 Asian Network for Scientific Information.
