الملخص

Code Division Multiple Access (CDMA) suffers from multi-user interference (MUI), and intersymbol interference (ISI) under frequency selective multi-path fading channels. Orthogonal Frequency Division Multiple access (OFDM) is MUI free but achieves lower diversity than CDMA system employing the same error control coding. Merging the advantage of OFDM and CDMA to minimize MUI and enable maximum available diversity for every user, multi carrier code division multiple access (MC-CDMA) is used.
In this paper the performance of group orthogonal multi-carrier code division multiple access (GO-MC-CDMA) system using multi-user detection is evaluated by simulation over two-paths frequency selective Rayleigh fading channel. Simulation results show that successive interference cancellation is better than parallel interference cancellation for higher signal-to noise ratio (SNR).
