These M-files are "Communications Toolbox" for classroom use. It is used by students taking a 4th year communications course where the emphasis is on digital coding of waveforms and on digital data transmission systems.

说明：  心电信号导入MATLAB 改一下PATH里的地址 一个心电信号有两路 这里两路的导入方式都有(ECG change it into MATLAB PATH in the address of a two-way ECG has written all the way here only import method)

用 LDPC 解码法，对原始信号通道的噪声进行评估，消去。具体原理可参照IEEE TCOM的论文。(Channel Noise Estimation or correlation estimation for distributed source coding Using Particle based Belief Propagation for LDPC decoding in AWGN and BSC models. This code is partially based on our published journal papers with some additional improvements. In this code, we removed the parameter lambda to reduce the number of free parameters. PBP estimator is distributed in the hope that is will be useful, but without any warranty. The codes have not been optimized, so the estimation speed may be slow. To use PBP estimator source code in your research, please cite our journal papers published in IEEE TCOM. )

二次多项式拟合大地水准面，采用matlab编写的，关于拟合出来的图像感觉有些问题。。希望大家指正(Quadratic polynomial fitting geoid, using matlab prepared some questions about the fitting out of the picture feel. . I hope you correct)
