Abstract

Switch and stay combining (SSC) diversity systems have the advantage of offering one of the least complex solutions to mitigating the effect of fading. We present a Markov chain-based analytical framework for the performance analysis of various switching strategies used in conjunction with SSC systems. The resulting expressions are quite general and are applicable to dual-branch diversity systems operating over a variety of correlated and/or unbalanced fading channels. The mathematical formalism is illustrated by some selected numerical examples along with their discussion and interpretation. As a result, the paper presents a thorough comparison and highlight the main differences and tradeoffs between the various SSC switching strategies.
