Unified Performance Analysis of Two Hop Amplify and Forward Relaying
Wireless relay networks have been studied extensively in the recent literature. Amplify and Forward (AF) is one of the most widely used type of relaying. Even though special cases such as channel-noise-assisted, channel-assisted and blind relay modes have been analyzed, a unified performance analysis seems to be not available. In this paper, the authors present unified performance analysis results for two-hop AF relaying over Nakagami-m fading nonidentical Source-to-Relay (S?¨R) and Relay-to-Destination (R?¨D) links. A general model for the received signal-to-noise ratio, which covers channel-noise-assisted, channel-assisted and blind relay configurations as special cases, is developed.
