Abstract
High speed data requirement among a large group of user is one of the key challenges in wireless communication. To meet this requirement adaptive multi-antenna system (adaptive diversity receiver) is a well known potential solution in wireless system design. Nevertheless, the ideal estimation technique which is considered to optimise the performance of a diversity receiver is difficult to get. Hence, in a practical scenario, the expected system performance of the receiver is considerably degraded. In this paper the average bit error rate (ABER) and capacity analysis has been studied for an arbitrary branch maximum ratio combiner (MRC) system for different modulation techniques over two wave diffused power (TWDP) fading channels with error in estimation.
