This paper analyses the effects of interference in multi-carrier communication in wireless channel and improves the system performance, in terms of Bit Error Rate (BER) using Multi-carrier Code Division Multiple Access (MC-CDMA) with Subcarrier Self-Cancellation (SSC) technique. SSC is performed for two successive subcarriers. Walsh Hadamard (WH) Code is used to spread the symbols. Simulation results show a significant improvement in performance by increasing the spreading code length with respect to the number of subcarriers. The performance of the system, in terms of BER and bandwidth efficiency, depends on the ratio between these two parameters.
