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)

针对通信侦查课题，通过已知先验知识和截获信号，进行找出同步序列，匹配滤波，校正频偏和相偏，均衡，解交织，译码，恢复出原序列，最终得到的序列与原序列作对比得到误码率为0(Investigation subject for the communication, by known a priori knowledge and intercepted signal conducted to identify the synchronization sequence, the matched filter, correcting frequency offset, and phase deviations, balanced, deinterleaving, decoding, to recover the original sequence, the resulting sequence with the original sequence compared error rate is 0)

Microsoft Visual C++ MFC串口通信编程详解,主要介绍了用CreateFile()函数和WriteFile()函数读写串口的实例,以及设置 串口属性的实例. 在工业控制中,工控机(一般都基于 Windows 平台)经常需要与智能仪表通过串口 进行通信.串口通信方便易行,应用广泛. 一般情况下,工控机和各智能仪表通过 RS485 总线进行通信.RS485 的通信方式是 半双工的,只能由作为主节点的工控 PC 机依次轮询网络上的各智能控制单元子节点. 每次通信都是由 PC 机通过串口向智能控制单元发布命令,智能控制单元在接收到正 确的命令后作出应答. (Microsoft Visual C++ MFC serial communication programming explain CreateFile () and WriteFile () function to read and write the serial port of the instance, and set the serial port attribute instance in industrial control, IPC (generally based on the Windows platform) often need to communicate with the smart meter through the serial port serial communication easy and widely used normal circumstances, the IPC and intelligent instrument through RS485 communication RS485 communication is half-duplex, only as the primary node industrial PC turn polling network intelligent control unit child nodes. every communication from a PC via the serial port to issue commands to the intelligent control unit, intelligent control unit receives the correct command response.)

基于MATLAB的瑞利分布仿真，对5条路径的瑞利信道进行了仿真(Rayleigh distribution based on MATLAB simulation, five-path Rayleigh channel simulation)

说明：  dco-ofdm接收机仿真，在matlab上仿真dco-ofdm的ser/Eb/N0曲线(The simulation of dco-ofdm receiver and the ser/Eb/N0 curve of dco-ofdm on MATLAB)

一个简单的verlog HDL教程，内容比较详细，可读性较高。(A simple verlog HDL tutorial, more detailed content, high readability.)

rs码通信系统的仿真实验，包括源程序和说明(rs code communication system simulation, including source and description)

在做毕业设计时编写的程序，主要内容是高铁环境下LTE系统的切换算法研究，源码中含scm信道模型。(a simulation about handover in LTE under high-speed railway station environment, which involving scm channel model.)

在OPNET上搭建场景，仿真接入算法，使用的是S-ALOHA接入算法，以仿真吞吐量、时延等性能(Build a scene on OPNET, simulation access algorithm, using the S-ALOHA access algorithm to simulate the throughput, latency and other performance)
