Cooperative Selection Diversity with CSI-Based Amplify-and-Forward Relaying in Nakagami-m Fading Channels

We derive new exact closed-form expressions for the symbol error rate (SER) of cooperative selection diversity (CSD) with amplify-and-forward (AF) transmission using channel-state-information (CSI)-based gain relaying. We consider the general fading condition of independent but not necessarily identically distributed (i.n.d.) Nakagami-m fading. We also present a closed-form expression for i.n.d. Rayleigh fading as a special case. We highlight the impact of the m fading parameter on the SER performance in unbalanced fading conditions. Numerical results substantiate the validity of our analysis.
