说明：  传输ofdm数据，采用了简单的多径信道，实现水下通信，整体程序还可以，可以参考参考(In order to transmit OFDM data, a simple multi-path channel is used to realize underwater communication. The overall program can also be used for reference)

说明：  DOA测向程序，包括遍历的角度误差，随时间变化的角度误差(DOA direction finding program, including traversing angular error, angular error over time)

基于MATLAB用窗函数设计FIR滤波器，并验证滤波效果(Design FIR filter based on MATLAB with window function and verify filter effect)

信息经格雷码映射，进行QPSK调制并通过AWGN信道发射，在接收端进行QPSK解调，并统计误符号率和误码率。(Information on the Gray code mapping, QPSK modulation and emission through the AWGN channel, QPSK demodulator at the receiving end, and the statistical symbol error rate and bit error rate.)

捷联惯性导航与GPS组合导航的matlab实现。采用自适应算法来对组合导航时行处理，并取得了很好的效果。

直接序列扩频原理仿真.用ELAINX公司SYSTEMVIEW调试.(Direct Sequence Spread Spectrum simulation theory. SYSTEMVIEW ELAINX companies with debugging.)

在光纤通讯仿真中，产生QPSK，16QAM，64QAM信号，并添加激光相位噪声和自发辐射噪声(In optical fiber communication simulation, QPSK, 16QAM, 64QAM signals are generated, and laser phase noise and spontaneous radiation noise are added.)

关于MATLAB GUI 串口通信的调试程序 ，发送好使，接收程序需要自己天加(About MATLAB GUI debug serial communication program)

说明：  本人用石川法求齿轮的啮合刚度，完整版的程序，里面可以运行啮合刚度图(Meshing Stiffness of Gears Calculated by Ishikawa Method)
