- 多功能实时手机定位监听软件简介： 1.只要输入对方的手机号码，对方在通话的时候有提示，你可以接听，对方是没有任何查觉的，如果你不能接听，软件会自动录音，把对方的通话录下来，你有时间的时候可以播放。 2.不限距离，全球范围内可以监听到任何无线电话。 3.目标号码随意更改，可同时监听6路通信设备。 4.短信拦截1000条，可以删除。-Multi-function monitor real-time mobile positioning software Descr iptio
16qam_channel_encode
- 一、 本程序采用16QAM调制方式，对一串2进制信源进行调制，采用（7，4）循环码对信源做信道编码，用升余弦滚降函数进行基带调制，再调到高频信道；在信道上加入高斯白噪声，运用匹配滤波器解调，画出解调星座图，运用最小欧氏距离译码判决，再对信号进行信道解码，画出采用信道编码技术和不采用信道编码技术的误比特率图。-First, this program uses 16QAM modulation mode, for a string of two binary source is modulated,
