Abstract—This paper evaluates the outage performance of CRNs with mutual interference between SUs and PUs under the underlay approach. We derive the outage probability expression of CRNs, and it is shown that the outage probability of CRNs with considering the interference to SU from PU is higher than that of CRNs without considering the interference to SU from PU. In addition, the outage probability is affected by key network parameters, such as maximum transmit power of SUs, transmit power of PU, interference level of PU, distribution parameter of transmission channel gain or the secondary transmission link (between the secondary transmitter to the secondary receiver) and distribution parameters of interference channel gain or interfering link (from the secondary transmitter to the primary receiver or from the primary transmitter to the secondary receiver). Simulation results have a good agreement with theoretical analysis.
Index Terms—Cognitive relay networks, outage probability, Rayleigh fading channel.
