Outage performance in relay-assisted overlay cognitive radio networks

Abstract: This paper investigates outage performance under overlay spectrum mode using relayassisted network model. Without harming the performance of the primary user (PU), secondary user (SU) makes use of a relay (R) for transmission as a supportive system besides the direct link transmission between secondary source (S) and secondary destination (D). Outage probability is used to represent the performance parameter for two different cases. In the first case, relay is able to forward the information from source to des… Show more

“…The outage probability closed-form expression is derived under the Rayleigh fading channel. The SU performance in relay-assisted overlay mode of CR network is analysed in [9]. Their simulation results showed the impact of distance on outage performance, where the outage probability increased with the increase in distance.…”
