频谱检测方法的仿真分析

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 , elaboratedtwo spectrum detection method, such as energy detection method and threshold detection method , energydetection method and threshold detection method are analyzed .In order to test the usefulness of the twodetection methods, two approaches are modeled and simulated in the Matlab platform , two methods wereanalyzed and compared about detection performance .
