This is a Tongxunlu system,very easy. 小型通讯系统，DOS界面。(This is a Tongxunlu system,very easy.)

opnet中aodv协议的模型，大家自己看好了(opnet in aodv protocol model, we own a good)

基本通信信号的产生于识别，AM FM 2ASK 2FSK 2PSK QPSK的产生。（时域图 频域图 基带信号频谱 ）以及分类的识别方法仿真模型(Basic communication signal arising from the recognition, the AM FM 2ASK 2FSK 2PSK QPSK generation. (Time-domain diagram frequency domain Figure baseband signal spectrum) and the classification of simulation models of the identification method)

function ber_ml=Alamoudi(snr,soglia) This function simulates a Alamouti scheme. The input variables are soglia and snr. Soglia: is the number of errors after which the iterations stop. For better results, put high value of soglia, but the simulation is longer. snr: the signal to noise ratio (if u don t know what is a signal to noise ratio, well, come back to your high school!). Note: U should use this function with a main function in wich u chose different value of snr. That s because this function work just with one value of snr. If u have problem with this code, write me at m.allegritti@email.it. Take care! Max

使用matlab进行毫米波信道模型仿真，很棒的源码(Millimeter-wave channel model simulation using matlab, great source code)
