web版微信协议分析。当前分析到登陆部分。举一反三，后续的拉取好友列表和发送消息等协议都好分析出来了。作者：孙强壮。(The web version of the micro-channel protocol analysis. Current analysis to the landing part. Giving top priority to, the subsequent pull friends list and send messages agreements out a good analysis.)

该文档为一个实现ofdm子载波调制和解调的代码，利用QPSK和16QAM两种方式实现，并附有运行结果。(This document is an implementation of ofdm subcarrier modulation and demodulation of the code, the use of QPSK and 16QAM two ways, along with operating results.)

关于联合信源信道编码的文章，来自IEEE，对于JSCC的研究很有参考价值(On the joint source-channel coding of the article, from IEEE, for the study of JSCC valuable)

RS码的FPGA实现，verilog语言形式，好参考资料(FPGA realization of RS code, verilog language form, a good reference)

Matlab仿真实现LDPC算法。BPSK调制，适用于AWGN信道(Matlab simulation implements the LDPC algorithm. BPSK modulation, suitable for the AWGN channel)

数字集群信道编解码程序，包括BCH和RCPC,属于欧洲ETSI Tetra标准。(digital trunking channel coding and decoding procedures, including BCH for RCPC and, European ETSI Tetra standard.)

昆仑通态触摸屏驱动脚本开发modbus程序源代码(MCGS driver script development MODBUS program source code)

朋友写的C++645通讯程序，支持645-1997与645-2007,支持自已组帧程序自动添加校验码通讯，可以增加数据标识定义，里面还有部分关于费控通讯代码，挺好，拿来分享(Friend write C++645 communications program to support the 645-1997 and 645-2007, to support their own group the frame program automatically adds the checksum communications, can increase data identifies the definition, there is also a section on the fee control communications code, good for them and share)

一种PTS算法在OFDM系统中降低PAPR，并且仿真出BER曲线。(A PTS algorithm in OFDM systems reduce PAPR, and simulation out BER curve )

说明：  OFDM仿真，包括仿真图，功率谱，星座图等(OFDM simulation, including simulation diagram, power spectrum, constellation diagram, etc.)
