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。

-Am program, first run through this program operator obtained a value of circular frequency　then run zhouqi.m procedures, a value determined by the cycle algorithm of signal detection　detection energy detection algorithm using the cycle detection algorithm was used to detect: : to run nengliang.m testing procedures, use energy detection to detect the signal. Testing is completed, analyze the detection performance.
