Cooperative Diversity with Blind Relays in Nakagami-m Fading Channels: MRC Analysis
Youngpil Song, Zahurul I. Sarkar, Hyundong Shin · 2008
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 m2are 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}.
