实现了LDPC码的编码 LDPC译码、LDPC校验矩阵的生成等。是完整的LDPC代码。测试了，跑的通。自学LDPC码的资料(Implements the LDPC encoding of LDPC decoding, LDPC check matrix generation and so on. LDPC code is complete. Tested and run through. Self-study of LDPC codes)

数字基带系统,运行无码间干扰数字基带传输特性及眼图的程序，观察所有的结果，对结果做出分析(Digital base-band system, running without inter-symbol interference digital base-band transmission characteristics and the eye diagram of the procedure, observe all the results of an analysis of the results)

这是研究欧洲DVB-T标准的一套合集，主要介绍了DVB-T单频网的同步技术，以及系统设计和实现。其中对DVB-T单频网进行了详细的讲解，对研究我国的数字电视广播技术也有很好的借鉴作用。(This is the study of the European DVB-T standard a collection, mainly introduces the synchronization technology of DVB-T single frequency network, and the system design and implementation. It make a detailed explanation of DVB-T single frequency network, also have a very good reference for digital television broadcast technology research in china.)

说明：  对接受到的调制信号的特征提取，用于调制识别(automatic modulation recognition)

在MATLAB上设计一个（2，1，3）卷积编码器和对应的采用维特比译码算法的译码器。编码器的生成多项式为：[1 0 1；1 1 1]。将编码器的输出经过一个高斯白噪声信道的结果作为译码器的输入，观察比较译码器输出和编码器输入，了解卷积码的容错性，并计算译码结果的误比特率.(A convolutional coder (2, 1, 3) and corresponding decoder using Vitby decoding algorithm are designed on MATLAB. The generating polynomial of encoder is: [1 01; 11 1]. The output of the encoder through a Gauss white noise channel as a result of the decoder input, compare the output of the decoder and encoder input, understand the fault tolerance of convolutional code, and calculate the decoding results of bit error rate.)
