The outage performance of cognitive opportunistic relaying (COR) systems with the interference at secondary user (SU) from primary user (PU) is analyzed over Nakagami-m fading channels. Specially, we derive an exact closed-form expression for the outage probability of the interested COR systems under the joint impact of the maximum transmission power PM at SU and the maximum interference power Q at...
The work focuses on the max link selection (MLS) schemes of buffer-aided relaying over the independent and non-identically distributed (i.ni.d) Nakagami-m fading channels in terms of outage probability, average packet delay, and improved diversity-delay trade-off schemes. By modeling the transition of buffer states as a Markov chain, we first obtain the outage probability and average packet delays...
