模拟调制解调：AM、DSB、LSB及FM。（通过AWGN噪声信道）(Analog modulation：AM、DSB、LSB and FM。)

knn algorithm used to calcule K-nearest neightbourgh programmed on Matlab application

说明：  本程序实现已知序列绘制其及傅立叶变换的图(the program known sequence mapping and Fourier transform their plans. .)

卫星运动学和姿态动力学模型，采用Matlab的S-function来创建模型，可以方便更改参数(Satellite kinematics and attitude dynamics model using Matlab S-function to create the model, you can easily change the parameters)

computer network: a optimization and control perspective

说明：  模拟缉私船追击变速走私船 加速到一定的速度，经过多久追上 并画出轨迹图！(Simulate how long it takes for the anti-smuggling vessel to chase the variable speed smuggling vessel to accelerate to a certain speed and draw the trajectory chart!)

几篇关于空时编码与cpm调制相结合的文章，非常实用，适合初学者(Several articles on the space-time coding and modulation combination cpm article, very useful for beginners)

this code reduce the dimentional of feature space using combine sparse matrix+PCA for classification eeg signal. more detail exixst inside the code. this code tested and work properly

这个是总结了各方面关于噪声的理解，主要是基于matlab计算信号时适用。(This is a summary of the understanding of all aspects of noise, mainly based on the calculated signal matlab apply.)
