Secrecy Outage Analysis of Spectrum Sharing Cognitive Radio Networks with Multiple Antenna
摘要
Abstract
This paper investigates the secrecy outage performance of maximal ratio combining(MRC) in cognitive radio networks(CRNs) over Rayleigh fading channels. In the considered system,a secondary us-er transmits confidential messages to another secondary user receiver,which is equipped with multiple an-tennas and adopts the MRC scheme to process multiple received signals. Meanwhile,an eavesdropper e-quipped with multiple antennas also adopts the MRC scheme to overhear the transmitted information be-tween secondary transmitter and secondary receiver. Secondary user transmitter adopts an underlay strategy to guarantee the quality of service of the primary user in spectrum sharing. This paper derives an exact closed-form expressions for the secrecy outage probability and analyzes the asymptotic performance. Simu-lation results validate the correctness of the analysis.关键词
