Communication related programs are really important to understand the working of the systems.

说明：  简单易懂的A-Law（13-segment) PCM的源代码,encode 的过程，适合初学者(Easy-to-read A-Law (13-segment) PCM source code, encode process, suitable for beginners)

自己设计的脉冲成形滤波器，采用matlab编码，并产生一个序列，输出经过成形后的波形(Pulse shaping filter design using matlab coding and generate a sequence, the output waveform after forming)

说明：  在matlab上面实现升余弦滤波器设计，不是用的matlab函数(In achieving the above raised cosine matlab filter design, not by the matlab function)

AM RECEIVER based on super heterodyne principle virtually used in all modern radio and television receivers. The approach mainly involves the use of heterodyning or frequency mixing. The signal from the antenna is filtered sufficiently at least to reject the image frequency and possibly amplified. A local oscillator in the receiver produces a sine wave which mixes with that signal, shifting it to a specific intermediate frequency (IF), usually a lower frequency. The IF signals is itself filtered and amplified and possibly processed in additional ways. The demodulator uses the IF signals rather than the original radio frequency to recreate a copy of the original modulation (such as audio). The project is coded in MATLAB.
