Performance Estimation of 2*3 MIMO-MC-CDMA in Rayleigh Fading Channel

In this paper we analyze the performance of 2*3 MIMO-MC-CDMA system in MATLAB which greatly reduces BER by increasing the efficiency of system. MIMO and MCCDMA system arrangement is used to decrease bit error rate and also figure a new system called MC-CDMA which is multiple user and multiple access system used to enhance the performance of the system. MC-CDMA is a narrowband flat fading in character which changes frequency selective to several narrowband flat fading multiple parallel sub-carriers to enhance the effectiveness of the system. Now this MC-CDMA further improved by grouping by 2*3 MIMO system which make use of ZF decoder at the receiver to reduce BER in which half-rate convolutional encoded Alamouti’s STBC block code is intended for channel encoding as transmit diversity for MIMO with multiple transmit and receive antennas. Main improvement of using MIMO-MC-CDMA is for reducing complication of system and also for dropping BER and finally increasing gain of the system. Then we estimate the system in different modulation techniques like, 64-QAM, 8-PSK, 16-QAM, QPSK, 32-QAM and 8-QAM using MATLAB in Rayleigh fading channel.
