经典的频谱共享的EI检索算法，运用动态频谱租用来提高频谱利用率。-Dynamic Spectrum Leasing (DSL) is a new paradigm for efficient spectrum sharing in cognitive radio networks that was recently proposed in [1]–[3]. Unlike in a hierarchical dynamic spectrum access (DSA) network,

认知无线电网络中，当信噪比不同时检测概率随虚警概率的变化曲线。-In Cognitive radio network,when the SNR is not the same, the change curve between the detection probability and the false alarm probability.
