Abstract: In recent years, multi-carrier techniques such as multi-carrier code division multiple access (CDMA) schemes have become popular in wireless communications over multipath fading channels. The MCCDMA used to improve security, data transmission rate and to minimise inter symbol interference (ISI). CDMA was suffering from multipath fading which affects its performance. In this research, the performance of multi-carrier code division multiple access (MC-CDMA) system is studied and evaluated, virtual frequency and phase synchronisation algorithm for the sub-carrier is proposed to reduce the BER of MC-CDMA. The simulation have been done using MATLAB programme, the results indicate that significant improvement in the system achieved under AWGN and Rayleigh fading channels using BPSK modulation. Increasing digital modulation orders and power have led to reduction in the BER for the system.
