Performance Analysis of BER Improvement for Multi Carrier CDMA System

Multi-carrier code division multiple access is an attractive choice for high speed wireless communication as it mitigates the problem of inter symbol interference and also exploits frequency diversity. In order to support multiple users with high speed data communications, the MC-CDMA technique is used to address these challenges. The work in this paper derives simulation result through MATLAB code of average bit error rate versus bit energy to noise ratio of Multicarrier Code Division Multiple Access systems using various pilot symbol estimation and detection techniques which are used for both uplink & downlink MC-CDMA systems i.e. MRC and MMSE. We simulate different equalization technique used in communication and compare the result and on the basis of that we will conclude that which technique will be best suited for future generation wireless communication. All the simulation is carried out on MATLAB tool. Index Terms— BER, Eb/No, MCCDMA, MMSE, MRC.
