Capacity enhancement with reduced complex receiver antenna selection algorithm for MIMO MC-CDMA system in mobile WiMAX networks

The MC-CDMA system achieves a high data rate through MIMO transceivers in frequency selective fading channel. The improvement in the performance and the reduction in complexity of MIMO system will lead to various applications. Hence there is a strong motivation for the high performance with reduced complexity and hardware. The processing of a large number of antennas can be reduced by antenna selection technique. In this paper, IBS (Iteration Based Selection) algorithm for antenna selection is proposed to remove the noisy signal´s based on iteration. This algorithm reduces the complexity for antenna selection with less reduction in capacity produced in MIMO-MC-CDMA system. The degradation in capacity and the complexity of selecting the best subset antenna is low when compared with existing methods.
