Abstract -
In this paper we estimate the performance of 2*3 MIMO-MC-CDMA system using convolution code in MATLAB which highly reduces BER by increasing the efficiency of system. MIMO and MC-CDMA system combination is used to reduce bit error rate and also for forming a new system called MC-CDMA which is multi user and multiple access schemes used to increase the performance of the system. MC-CDMA system is a narrowband flat fading in nature which converts frequency selective to numerous narrowband flat fading multiple parallel sub-carriers to increase the efficiency of the system. Now this MC-CDMA system can also be enhanced by grouping with 2*3 MIMO system which utilizes ZF decoder at the receiver to decrease BER in which ½ rate convolutionally encoded Alamouti STBC block code is used for channel encoding scheme as transmit diversity of MIMO with multiple transmit antenna. And convolution encoder is also used as source encoder or FEC encoder in MIMO-MC—CDMA. Advantage of using MIMO-MC-CDMA using convolution code is due to reduce complexity of system and also for reducing BER and finally to increase gain of system. Now after this we examine system in various modulation techniques like, 8-PSK, 16-QAM, QPSK, 32-QAM, 8-QAM and 64-QAM using MATLAB in Rayleigh fading channel.
