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.

采用LDPC编码对随机的二进制序列进行纠错编码和基带调制，在AWGN信道上进行传输，然后在接收端并采用合适的方式进行解调和译码，最后对纠错编码的性能加以分析。(LDPC codes using random binary sequence of error-correcting coding and base-band modulation, for transmission in the AWGN channel, and then at the receiving end and use the appropriate manner demodulation and decoding, error correction coding on the performance of the final analysis.)

说明：  在用matlab的时频分析中，不是所有信号的wvd都是可以，一些特殊的信号要用特殊的窗口来得到较好的效果(using Matlab in the time-frequency analysis, not all signals can be wvd, some special signal use special window to get good results)

This a two dimensional level set code where the interface grows with normal speed equal to one. The code generates a movie showing the interface motion. This code uses a first order Godunov method.
