OFDM系统经典均衡MATLAB程序, 包括ZF均衡，MMSE均衡，RLS均衡(ZFE ,mmse, rls,for OFDMsystem )

wince傳送簡訊的範例,利用vs 2005編譯開發(wince newsletter send an example, using vs 2005 to compile the development of)

空域零陷，首先用doa技术估计直达波方向，然后置零，用于直达波消除。(In spatial nulling, DOA technique is used to estimate the direction of direct wave, and then zeroing is used to eliminate direct wave.)

在n个城市建设通信网络，只需架设n-1条线路即可至少包含10个城市，城市数n由键盘录入，城市坐标由随机函数产生小于100的整数(In the construction of communication network in n cities, only n-1 lines are needed to include at least 10 cities. The number of cities n is input by keyboard, and the coordinates of cities are generated by random functions into integers less than 100.)

说明：  该资源为应用GNUradio工具，对USRP的开发，主要实现了频谱感知，以及根据频谱感知的结果进行ofdm通信的功能(This resource is the development of USRP using gnuradio tool. It mainly realizes the function of spectrum sensing and OFDM communication according to the result of spectrum sensing)
