：随着无线技术的飞速发展，频谱缺乏已经成为一个非常严重的问题．感知无线电技术能有效解 决频谱紧张的现状．介绍了感知无线电概念及其内涵，然后介绍了检测频谱空穴的方法．为提高检测概率、 降低设备复杂度及计算复杂度，将UWB与感知无线电结合，提出了基于能量检测及用户合作（EDAUC）的 协作感知方法．仿真和分析表明：该方法能有效提高检测频谱空穴的概率．(: With the rapid development of wireless technology, the lack of spectrum has become a very serious problem. Cognitive radio technology can effectively solve the spectrum tense situation. Introduced the concept of cognitive radio and its content, and then introduces the method of detection of spectrum holes. To improve the detection probability and reduces the complexity and computational complexity, the combination of UWB and cognitive radio is proposed based on energy detection and user cooperation (EDAUC) the cooperative sensing methods. Simulation and analysis: This method can improve the probability of detection of spectrum holes.)
