Effect of Channel Estimation Errors on the Performance of a M-MRC Receiver over TWDP Fading Channels

摘要

To meet the demand high-speed data requirement multi-antenna (diversity) systems are well-accepted technique. These types of communication receivers use estimators to optimize the performance. However, an ideal estimator is challenging to obtain which leads degradation of the expected performance of the diversity system. This paper analyzes the outage and average bit error rate (ABER) performance of an arbitrary branch maximal ratio combining (MRC) receiver over two wave diffuse power (TWDP) fading channel with errors in the estimator. The analysis of the obtained results shows that the estimation error is a significant component of the design aspect and can't be neglected.
