Abstract

The demand for the wireless communication is increasing enormously. Multiple Input and Multiple Output (MIMO) systems are helpful in this regard. The Multicarrier systems are designed with the combination of different space time coding techniques for fulfilling this demand. Multicarrier Code Division Multiple Access (MC-CDMA) with Alamouti´s Space Time Block Codes (STBC) is one of them. The Genetic Algorithm (GA) is used to provide assistance in order to optimize the weights of MC-CDMA receiver. This receiver has better convergence rate than simple LMS receivers. The Bit Error Rate (BER) is also comparable at low and high Signal to Noise Ratio (SNR).
