盲源分离在通信侦查中的应用，适用于通信侦查的盲源分离解决方案。很不错的文章(Application of blind source separation in the Investigation of the communication, for communication investigation blind source separation solutions. Very good article)

APDL 培训资料，很好的学习ansys的资料(APDL training materials, information on good learning ansys)

ModBus水质分析仪CRC计算的接口STM32F2实现，此应用适用于市面大部分Modbus水质协议的CRC校验(ModBus water quality analyzer CRC calculation of the interface STM32F2 implementation, this application is applicable to most of the market Modbus water quality agreement CRC calibration)

（1）请推导出单径瑞利信道中的BPSK相干解调的理论误码率性能，并画出比特信噪比与误码率的关系曲线。 （2）在单径瑞利信道中，请设计一种时分的导引辅助的信道估计方法，用Simulink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(1)的曲线进行对比。 ((1) derived from single-Path Rayleigh channel coherent demodulation of BPSK theoretical bit error rate performance and draw-bit signal to noise ratio and bit error rate curve. (2) in a single Path Rayleigh channel, please design a guided night-assisted channel estimation methods, using Simulink simulation, surveying BPSK BER performance, drawn-bit signal to noise ratio and bit error rate curve, and with (1) comparing the curve.)

说明：  此工程用Visual Studio 2019 编写，目的是用来替换Thorlabs公司自己的GUI Kinesis来控制TDC001伺服电机控制器,方便用户自己控制。(This project is written in Visual Studio 2019. The purpose is to replace the GUI kinesis of thorlabs company to control the tdc001 servo motor controller, which is convenient for users to control by themselves.)

基于PARKER9000运动控制器的上位机程序开发，包括单轴点动以及多轴联动(Based on PARKER9000 motion controller host computer program development, including uniaxial jog, and multi-axis)

这是 Okumura 和Hata模型的编码。(This is the coding of Okumura and Hata models.)
