Island differential evolution based adaptive receiver for MC-CDMA system

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. In this paper, Island Differential Evolution (IDE) Algorithm is applied to MC-CDMA receiver in order to find out the weight vectors. This receiver is studied for Fast Fourier, transform (FFT) and Slantlet Transform (SLT) separately. We find out that SLT-MC-CDMA give, overall attractive Bit Error Rate (BER) as compare to, FFT-MC-CDMA system. The IDE Algorithm gives attractive BER for all SNR values in both SLT and, FFT based MC-CDMA system.
