摘　　要：针对目前无线电频谱检测的相关方法和技术,阐述了频谱检测技术中的能量检测法和门限检测法,并对这2种方法进行了分析。为了检验2种检测方法的有用性,在Matlab平台下对这2种方法进行了建模仿真,分析并比较2种方法的检测性能。According to the related method and technology of radio spectrum detection, elaborated two spectrum detection method, such as energy detection method and threshold detection method, energy detection method and threshold detection method are analyzed. In order to test the usefulness of the two detection methods, two approaches are modeled and simulated in the Matlab platform, two methods were analyzed and compared about detection performance.
