摘要

In this paper, we explore the cognitive cloud radio access networks with cooperative spectrum sensing in the presence of hardware impairment. Multiuser diversity technique is considered in order to enhance system capacity and improve the reliability of transmission. To avoid interfering with the primary user's communications, the BS intends to transmit messages towards the secondary user only when the spectrum hole is detected. Exact closed form expression for the outage probability of the system understudy is derived over Rayleigh fading channels. It is shown that the hardware impairment degrades the performance of the secondary system. Finally, simulation results are presented to verify the correctness of our analytical derivations.
