This work is done by someone else. I m only uploading it to share with you.

Implement a differential encoder for the case M=8DPSK

基于期望最大化的时变参数建模，时频分辨率高(Based on expectation maximization of time-varying parameter modeling, high time-frequency resolution)

基于复合形法的最优控制m文件，以实现可直接使用(M files based on optimal control complex method to achieve can be used directly)

仿真实现了十三位巴克码进行脉内调相。很好的程序，亲自优化过。(Thirteen Barker codes are simulated for intra-pulse phase modulation. Good procedures, personally optimized.)

source code HMM for matlab

Backpropagation, an abbreviation for backward propagation of errors , is a common method of training artificial neural networks used in conjunction with an optimization method such as gradient descent. The method calculates the gradient of a loss function with respects to all the weights in the network.

基于SIMULINK的PID控制器设计与仿真 在第二个和第三个环节之间有累加的扰动输入即：在 5 秒时，幅值为 0.5 的阶跃扰动；控制器为Gc(s) ，反馈环节 H (s )= 1。设定值为0 秒幅值 1 的阶跃信号。(SIMULINK-based PID controller design and simulation)
