Code division multiple access (CDMA) suffers from intersymbol interference (ISI) and multi-user interference (MUI) in a frequency-selective multipath fading channel, but when properly designed, it enjoys multipath diversity. Orthogonal frequency division multiple access (FDMA) is a promising MUI free but it dose not enable the multi-path induced diversity without employing error control coding. Group Orthogonal Multi-carrier CDMA (GO-MC-CDMA) merges the advantages of OFDMA and CDMA systems. In this paper, frequency domain equalizer (FDE) is applied to the reception of GO-MC-CDMA to minimize MUI and enable maximum available diversity for every user. Four types of FDE are considered; minimum mean-square error (MMSE)-FDE, equal gain combining (EGC)-FDE, maximal-ratio combining (MRC)-FDE and zero-forcing (ZF)-FDE. As demonstrated in simulations, MMSE-FDE achieves better performance among other considered frequency domain equalizers.
