摘要：
The outrage behavior of a dual-hop multi-source multi-relay cooperative underlay cognitive radio network is investigated in the presence of multiple primary transmitters and multiple primary receivers. First, with Primary Users' (PUs') outrage constraints, an adaptive power control scheme is adopted to adjust the secondary transmission power. Then, an SINR-based scheme is proposed to investigate the outrage platform performance of the underlying cognitive radio network. In this context, exact closed-form expressions for the outrage probability of reactive Decode-and-Forward (DF) relaying are derived for the Maximum Ratio Combining (MRC) and Selection Combining (SC) over Rayleigh fading channels, respectively. In particular, the dependence among the received Signal-to-Interference-plus-Noise Ratios (SINRs) is considered at the destination caused by multiple PUs. It is shown that although there exists outrage floor in the high Signal-to-Noise Ratio (SNR) regime, increasing the number of the secondary sources or available relays is an efficient way to decrease the outrage floor. © 2019, Editorial Board of Jilin University.
