中文说明：LDPC码的完整的编译码，部分实现了追踪测速迭代松弛算法，一些自适应信号处理的算法，保证准确无误，是学习通信的好帮手，滤波求和方式实现宽带波束形成，考虑雨衰 阴影 和多径影响。
English Description：
The encoding and decoding of LDPC codes, part of the implementation of the tracking velocimetry iterative relaxation algorithm, some adaptive signal processing algorithm to ensure accurate, is a good helper to learn communication, filtering and summation way achieve broadband beam formation, consider rain attenuation shadowing and multipath effects.
