摘要: In this paper we investigate the bit-error-rate (BER) performance of Multicarrier Code Division Multiple Access (MCCDMA) systems assuming Minimum Shift Keying (MSK) and Maximal Ratio Combining (MRC) in Fading Channels. We provide accurate closed-form BER formulas. The studied system is assumed to have synchronous users, each user's data be spread using long random spreading codes. analysis includes independent correlated Nakagami-m Rician fading channels. Furthermore, effect frequency offset also considered. Moreover, derived expressions are verified via simulation, as will shown, simulated results agree well with theoretical expressions.
