按键式电话如下图所示，当按下某一个键时会产生如图所示的相应的频率模拟信号，并通过对该信号频率的检测，识别出对应的按键。试通过编写一个数字信号分析程序，模拟完成上面的功能。(Touch-tone phone as shown below, when pressing a key will be generated as shown in the corresponding frequency analog signals and, through detection of the signal frequency to identify the corresponding button. Test through the preparation of a digital signal analysis program to simulate the function of the completion of the above.)

这是一个关于自相关算法及功率谱的仿真的源代码... (matlab This is the one on self-correlation )

2PSK和 2DPSK信号的调制与解调性能比较分析 基于matlab的仿真(Comparative analysis of modulation and demodulation performance and 2DPSK signal 2PSK)

说明：  此程序描述了QPSK调制解调的过程，包括成形与匹配滤波，最后给出解调误码率。(This program describes the process of QPSK modulation and demodulation, including shaping and matching filtering, and finally gives the demodulation error rate.)
