根据流程图搭建并且仿真OFDM系统，画出输入输出的信号的星座图，计算误码率，改变抽头系数……(According to the flow chart, the OFDM system is built and simulated. The constellation diagram of the input and output signals is drawn, the bit error rate is calculated, and the tap coefficient is changed.)

这是射线信道模型的代码。里面有多个m文件(This is the code for the ray channel model. There are multiple M files in it.)

QPSK开环载波同步技术研究 频偏估计算法(Open-loop carrier synchronization QPSK Research Frequency Offset Estimation Algorithm)

OPNET14.5的帮助文档，几乎所有的现行阶段的教材都是由该软件帮助文档改编或缩减而成，所以该文档为OPNET学习者必备手册之一。(OPNET14.5 the help of documents, almost all of the current phase of the teaching materials are adapted to the software help files or reduced form, so the document must have the manual for one of OPNET learners.)

modbus rtu 校验vb源码，对VB学习者很有帮助(modbus rtu checksum vb source code, useful for VB learner)

说明：  在单径瑞利信道中，设计一种时分的导引辅助的信道估计方法，用Simulink和m语言进行仿真，测量BPSK的误码率性能，画出比特信噪比与误码率的关系曲线，并与理论误码率曲线进行对比(In the single path Rayleigh channel, a time-division guidance aided channel estimation method is designed. The simulation is carried out with Simulink and M language. The BER performance of BPSK is measured, and the relationship curve between bit signal-to-noise ratio and BER is drawn, and compared with the theoretical BER curve)
