这组代码模拟了整个信号的编码，调制，解调，译码在无线通信，其中包括A-law扩展，PCM和的2PSK调制解调的技术过程。(This collection of codes simulates the whole signal encoding, modulation, demodulation, decoding process in wireless communication, which involves the techniques of A law companding, PCM, and 2PSK modulation and demodulation.)

Matlab M-Files:There are four ways of doing code in Matlab. One can directly enter code in a terminal window. This amounts to using Matlabas a kind of calculator, and it is good for simple, low-level work. The second method is to create a script M-fi le. Here, one makes a fi le with the same code one would enter in a terminal window. When the fi le is “run”, the script is carried out. The third method is the function M-fi le. This method actually creates a function, with inputs and outputs. The fourth method will not be discussed here. It is a way to incorporate C code or FORTRAN code into Matlab this method uses .mex fi les. We will not disucss it here.
