Cognitive radio allows unlicensed users to access licensed frequency bands through dynamic spectrum access so as to reduce spectrum scarcity. This requires intelligent spectrum sensing techniques like co-operative sensing which makes use of information number of users.

以Excel表格保存下来的的交流电压电流波形的离散数据（这些数据从示波器中导出来），本matlab程序可以进行FFT分析，分析电压和电流谐波含量,THD大小。注意，每次只能分析一组数据。(Excel matlab FFT )

说明：  gaosi 信道的m文件,通信中必须要的仿真文件(m channel gaosi documents, communication must be of the simulation file)
