Abstracts: In direct Sequence spread spectrum transmission, the user data is multiplied by a binary code sequence. And the receiver side, the coded signal is again multiplied by same code sequence to get original signal back. Analysis of the Bit Error Rate (BER) will be carried out for a Multi Carrier CDMA wireless communication link considering the effect of channels limitations like fading, delay spread etc. Different schemes of MC-CDMA will be considered and performance result will be evaluated by numerical computations. Performance degradations due to above system impairments will be evaluated and optimum system design parameters will be determined. In this project bit error rate performance of MC-CDMA and DS-CDMA systems with SNR will be carried out by MATLAB simulation. In this project we will compare BER performance for both CDMA systems and find out which CDMA system is good for communication among DS-CDMA and MC-CDMA.
