Abstract
A comprehensive study regarding the diversity and coding gains of fixed-gain amplify-and-forward dual-hop relaying systems with partial relay selection is performed. Our analysis allows for arbitrary independent Nakagami-m fading channels with distinct fading parameters among the links. It is shown that the diversity gain is determined by the minimum of the fading parameter pertaining to the selected relay-destination link and the sum of that of the source-relay links. Simulation results are presented to corroborate the proposed methodology.
