信号仿真

代码说明：

说明：  对常见的调制信号在软件无线电的通用平台下进行调制解调。所有信号均通过正交分解后，在一个同用的平台上进行调制，然后通过各自的解调算法解调。(right common modulation radio signals in the software under a common platform for modulation and demodulation. All signals are orthogonal decomposition, the same one used on the platform for modulation and demodulation through their respective demodulation algorithm.)
