Average level crossing rate of microcellular mobile radio system with selection combining in the presence of arbitrary number of cochannel interferences

Abstract

This paper provides an exact and rapidly converging infinite-series expression for the average level crossing rate of dual selection combining receiver in a communication system with a Rician desired signal affected by multiple Nakagami-m cochannel interferences. The branch selection is based on the desired signal power algorithm with input signals assumed to be correlated because of insufficient distance between diversity branches. The proposed mathematical analysis is complemented by various numerical results showing the effects of various system's parameters. Copyright © 2011 John Wiley & Sons, Ltd.
