基于能量检测和周期循环检测的认知无线电频谱检测matlab代码
用周期循环检测算法检测：
首先运行a.m程序，通过此程序运算得出循环频率a值；
再运行zhouqi.m程序，对a值进行确定，通过周期循环算法对信号进行检测；
用能量检测算法检测：
运行nengliang.m检测程序，使用能量检测对信号进行检测。
检测完毕，对检测性能进行分析。

谱感知技术是认知无线电(CR)的关键技术,频谱检测的可靠度和精度决定了是否会影响主用户的正常通信及认知用户能否有效利用频谱.在频谱检测的众多方法中,能量检测法是一种常用的方法,但能量检测器的门限很容易受到噪声功率变化的影响,影响主用户的正常通信.笔者提出一种自适应背景噪声的门限设置方法,通过引入门限评价指数作为衡量频谱感知效率和频谱资源利用率的度量指标,使得认知用户在不同的应用环境中能自适应地设置频谱感知门限,达到更充分利用频谱资源和更有效传送信号的目的.仿真证明,该方法确定的门限能够随着噪声条
