研究了底层认知无线电(CR)网络中全双工(FD)模式的最佳解码转发(DF)中继选择的性能分析，分析了残余自干扰、接收信噪比(SNR)分布和中断概率等关键参数的影响。与半双工（HD）模式的传统中继选择方案不同，FD中继由于使用同一信道同时发送和接收而受到残余自干扰的影响。此外，推导了独立 Nakagam 和 Rayleigh 衰落信道上所提出的 FD 中继选择方案的中断概率的精确闭式表达式，并通过仿真证明了所提出分析的有效性。数值结果表明，在存在多个候选中继的情况下，在（10 dB，15 dB）的信噪比范围内，始终可以实现中断概率方面的最佳中继选择解决方案。
The performance analysis of optimal decode-and-forward (DF) relay selection for the full-duplex (FD) mode in underlay cognitive radio (CR) networks is studied, with the impact of critical parameters such as the residual self-interference, the distributions of the received signal-to-noise ratio (SNR), and the outage probability, being analyzed. Different from the conventional relay selection schemes with half-duplex (HD) mode, the FD relay suffers from the impact of residual self-interference due to its simultaneous transmission and reception using the same channel. Furthermore, the exact closed-form expressions for the outage probabilities of the proposed FD relay-selection scheme over both independent Nakagami- m and Rayleigh fading channels are derived, with the validity of the proposed analysis being proven by using simulation. Numerical results show that, in the presence of multiple candidate relays, an optimum relay-selection solution in terms of outage probability can always be achievable within the SNR range of (10 dB, 15 dB).
