摘要: This letter presents a unified framework for the outage performance analysis of cognitive opportunistic amplify-and-forward relay networks with direct link using maximum ratio combining (MRC) and selection (SC) schemes in presence multiple primary receivers. Specifically, we derive closed-form expressions probability asymptotic behavior both under Nakagami- $m$ fading. We manifest analytically that network affects only coding gains these schemes, not diversity are found to be same cases. Moreover, provide an analytical high signal-to-noise (SNR) gap expression between two which is shown independent parameters. Numerical simulation results validate our theoretical analysis.
