In this paper, we propose a novel derivation approach to obtain the exact closed form expression of ergodic capacity for cognitive underlay amplify-and-forward (AF) relay networks over Rayleigh fading channels. Simulation results are performed to verify the analysis results. Numerical results are provided to compare the system performance of cognitive underlay amplify-and-forward relay networks under both cases of AF and decode-and-forward (DF) confirming that the system with DF provides better performance as compared with that with AF.

Form Expression

The outage probability (OP) of dual-hop fixed-gain amplify-and-forward (AF) relay over Rayleigh fading channels is analyzed when the feedback delay, the estimation error and the multiple co-channel interferences (CCI) are all present. A closed-form expression for the OP is derived and validated by Monte Carlo simulations with several scenarios considered, also the impacts of feedback delay, estimation error and CCI have been shown in the numerical results.
