摘要：
This paper investigated cognitive relay networks with practical distributed switch-and-stay combining (DSSC) protocol when considering the primary transmitter's interference to secondary network. The closed-form expressions for the outage probability is derived, the correctness of the analysis is validated by Monte Carlo simulations and readily allows us to evaluate the impact of the key system parameters on the performance. The analytical results reveal that the proposed DSSC scheme has optimal switch threshold, and it is not the threshold SNR for the outage, which is true for the model without the interference from primary transmitter, and increasing the switching threshold do not always improve the system performance. The asymptotic analysis also reveals that the outage diversity only achieves one, which is also different from the traditional relay network with DSSC protocol.
