Performance Analysis of MC-CDMA in Rayleigh Channel Using Walsh Code with BPSK Modulation

High Speed data rate communication is possible with the help of the Multi Carrier Code Division Multiple Access (MC-CDMA). Inter symbol Interference (ISI) and frequency diversity problems are resolved by MC-CDMA. This paper analyzes the performance of MC-CDMA in the presence of Additive White Gaussian noise using a BPSK modulator in Rayleigh fading channel. The results based on various combining techniques for different users are simulated and compared using MATLAB software.
