Performance analysis of partial relay selection networks with multiple-antenna destinations
L M R Somaweera · 2010
The performance of dual-hop cooperative relay networks with partial relay selection is studied. Specifically, the system model consists of a single-antenna source, single-antenna L relays and a multiple-antenna destination. Both fixed-gain amplify-and forward (FG-AF) and decode-and-forward (DF) relays are treated. The best relay is selected based on instantaneous and partial knowledge of the source-to-relay channel state information. The cumulative distribution function of the end-to-end signal-to-noise ratio (SNR) is derived in closed form and used to obtain the exact outage probability and the average symbol error rate. These performance metrics are used to compare the performance of FG-AF and DF relays against the channel-assisted amplify-and-forward (CA-AF) relays. The analysis is verified throughly by using Monte-Carlo simulation results.
