Exact outage probability of cognitive relay networks over non-identically distributed Rayleigh fading channels
摘要
Abstract
The outage performance of the secondary user is investigated for cognitive relay networks with underlay spectrum sharing model.An exact closed-form of outage probability is derived over independent but non-identically distributed (non-i.d.)Rayleigh fading channels.The derived formula is verified by Monte-Carlo simulations and is served as an effective tool to evaluate the outage performance under differ-ent channel parameters.Simulation results show that the channel state of the relaying link (ST → SR ) and the interference link (ST → PD )dominate the outage performance in cognitive relay networks.关键词
