说明：  基于SimuLink的数字通信链路仿真 包含QPSK及16QAM模式下的链路计算(Simulation of digital communication link based on Simulink Including link calculation in QPSK and 16QAM mode)

西门子STEP7，费斯托阀岛的GSD文件，硬件组态使用(SIEMENS STEP7, GSD File of Fisto Valve Island, Hardware Configuration Use)

详细的讲述了linux的ip/tcp通信部分的协议栈，对开发很有帮助(Linux detail of the ip/tcp communication part of the protocol stack, on the development of useful)

ofdm系统matlab仿真m程序，包括信道编解码，多径信道，信道估计以及误码率统计等功能(matlab simulation m OFDM system procedures, including channel coding and decoding, multi-path channel, channel estimation, as well as features such as bit error rate statistics)

进行信号积累时，有的信号存在多普勒频率，不利于累加。该程序可完成对信号多谱勒频率的补偿。(Signal accumulation, some signal Doppler frequency, is not conducive to the accumulation. The program can be complete compensation of the signal Doppler frequency.)

实现使用music算法进行频率估计，并绘图(Achieve the use of music algorithm for frequency estimation, and graphics)

这个是华为的VoIP文档，讲述清晰，值得阅读！(This is Huawei' s VoIP documents, about clarity, it is worth reading!)

说明：  4098QAM编码在AWGN信道下误码率性能与Eb/N0（信噪比）的关系(The performance of 4096QAM at AWGN channel: BER~Eb/N0)

最大比合并功能实现，简单代码，容易看懂，MATLAB源代码(Functions to achieve the maximum ratio combining, simple code, easy to understand)

最近在做毕设，ldpc码的编解码实现，这个是verilog实现。(Recently completed the set up to do, ldpc code codec implementation, this is the Verilog implementation.)
