Abstract
The performance of dual-hop channel-noise-assisted amplify-and-forward cooperative networks with relay selection in a clustered structure is evaluated. Exact closed-form expressions for the probability density function and cumulative distribution function of the end-to-end signal-to-noise ratio (SNR) are derived. Making using of these expressions, the average symbol error probability (SEP) and ergodic capacity are numerically evaluated. In addition, a highly accurate closed-form approximate expression for the average SEP and a closed-form upper bound for the ergodic capacity are derived. Numerical examples are plotted in order to illustrate the efficiency of our formulations.
