简介
In this letter, considering a cognitive relay network with the maximum transmit power limit in a spectrum sharing scenario, the exact outage probability of secondary system is derived over Rayleigh fading channels, and the theoretical analysis is validated by simulations. The results show that both the maximum transmit power limit and the interference power constraint cause the outage saturation phenomenon, and more relays for secondary system can provide better outage performance.
