Abstract

We derive the exact maximal-ratio combining (MRC) performance of dual-hop cooperative diversity systems with L-antenna destination reception in Nakagami-m fading channels, where a single-antenna relay operates in semi-blind (fixed-gain) amplify-and-forward (AF) mode. We also show that if m₀, m₁, and m₂ are the respective Nakagami parameters for the source-to-destination, source-to-relay, and relay-to-destination links, the semi-blind AF cooperation with MRC achieves the diversity order of m₀L + min {m₁, m₂L}.
