In this paper, the impact of Forward Error Correction (FEC) code namely Trellis code with interleaver on


the performance of wavelet based MC-CDMA wireless communication system with the implementation of


Alamouti antenna diversity scheme has been investigated in terms of Bit Error Rate (BER) as a function of


Signal-to-Noise Ratio (SNR) per bit. Simulation of the system under proposed study has been done in M-ary


modulation schemes (MPSK, MQAM and DPSK) over AWGN and Rayleigh fading channel incorporating


Walsh Hadamard code as orthogonal spreading code to discriminate the message signal for individual


user. It is observed via computer simulation that the performance of the interleaved coded based proposed


system outperforms than that of the uncoded system in all modulation schemes over Rayleigh fading


channel.
