基于认知无线电（CR）的频谱共享技术为解决频谱资源短缺问题而备受关注。在频谱共享环境下，从用户可以在主用户处的干扰约束下，使用授权给主用户的频段。为了通过设置合适的频率、发射功率等通信参数，实现高效的频谱共享，对无线环境的准确识别至关重要。
Spectrum sharing with cognitive radio (CR) has attracted attention to solve the shortage of spectrum resources. In a spectrum sharing environment, secondary users (SUs) can utilize spectrum bands which are licensed to primary users (PUs) under interference constraint at PUs. In order to gain the spectrum sharing efficient by setting suitable communication parameters of SUs such as frequency and transmission power, it is important to accurately recognize the radio environment.
