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.
