Effect of Mutual Coupling on BER Performance of Alamouti Scheme

Abstract

This work presents a study on the effect of mutual coupling on the performance of Alamouti scheme by studying the bit error rate (BER) performance under different propagation scenarios and for different coupling cases. We show that the presence of mutual coupling may have positive or negative impact on the achieved power gain depending on the correlation properties of the propagation environment in absence of the coupling effect and on the mutual coupling matrix
