实现LDPC码校验矩阵的构造，采用Mackay 1A方法(Implementation of LDPC code check matrix construction uses Mackay 1A method)

采用H323协议的ip电话通信系统，可以移植裁剪应用。(Ip with H323 protocol telephone system, portable cutting applications.)

说明：  本文主要从自适应调制的算法及实现出发，引入了OFDM子载波分组的概念，详细阐述了五种固定阈值算法和子带BER预估计算法的原理及实现，并在此基础上加入自适应编码，实现自适应调制与编码。(Based on the algorithm and implementation of adaptive modulation, this paper introduces the concept of OFDM subcarrier grouping, elaborates the principle and implementation of five fixed threshold algorithms and subband BER estimation algorithm, and adds adaptive coding to realize adaptive modulation and coding.)

说明：  载波同步仿真，使用的是反馈补偿法，接收信号经补偿矩阵，误差提取，环路滤波，相位累加器后反馈回补偿矩阵，稳定后估计相位趋近相位差，存在相位模糊情况。(the simulation of the carrier synchronization)
