Multi-Carrier Code Division Multiple Access (MC-CDMA) is one of the advanced technique which supports various multimedia services such as image, data, speech, audio and video provided by the today's diverse wireless communication systems. In this paper, we investigate the Bit Error Rate (BER) performance of MC-CDMA system with Zero Forcing (ZF) and Minimum Mean Square Error (MMSE) equalization techniques through MATLAB simulation. The simulation has been carried out using Binary Phase Shift Keying (BPSK) and Quadrature Phase Shift Keying (QPSK) modulation techniques along with ½ rate convolution coding over frequency selective Rayleigh fading channel. Simulation results show the effects of different parameters such as the number of users, equalization techniques, modulation techniques and convolutional coding on the performance of MC-CDMA system.

The paper describes the performance of convolution coded Multicarrier Code Division Multiple Access (MC-CDMA) system evaluated for different equalization techniques i.e. Maximal Ratio Combining (MRC) and Equal Gain Combining (EGC) in frequency selective Rayleigh channel in detail. For symbol mapping two modulation techniques: Binary Phase Shift Keying (BPSK) and Quadrature Phase Shift Keying (QPSK) is used. The comparison is done between the performances of MC-CDMA system with convolution codes and without convolution codes for different equalization and modulation techniques in terms of Bit Error Rate (BER) and Signal to Noise Ratio (SNR) using MATLAB based simulation. Simulation results reveal better SNRs when ½ rate convolution coding is used with different modulation techniques.
