Physical Layer Security Performance Analysis of Spectrum Sharing CR-NOMA System Based on Decode-and-Forward
摘要
Abstract
The physical layer security(PLS)in cognitive radio(CR)networks based on non-orthogonal multiple access(NOMA)network is analyzed.Considering an existing eavesdropper,the NOMA-based CR transferes data with the decode-and-forward collaborative mode over Nakagami-m channel.To analyze the performance of NOMA-based CR networks in PLS perspective,the security performance is evaluated by the closed-form expressions for connection outage probability and secrecy outage probability.Furthermore,Monte Carlo simulations are provided to verify the derived analytical results and the impact of parameters on system performance is analyzed.关键词
