说明：  本程序为OFDM系统中基于LSE的信道估计(This procedure for the OFDM system channel estimation based on the LSE)

一个正弦波利用DCT，FFT变换后稀疏化，然后应用压缩感知实现压缩，并有仿真图例说明重构效果。重构算法采用线性规划和OMP算法等，是一个初学CS入门的好例子。(A sine wave using DCT, FFT transform sparse, and then apply compressed sensing to achieve compression, and a legend reconstruction simulation results. Reconstruction algorithm using linear programming and OMP algorithms, is a good example of beginner CS entry.)

用MATLAB实现动态系统的求导与积分函数(MATLAB diff and int)

用LSB算法做图片隐藏，提取及检测，适合初学者学习参考(LSB algorithm to do image extraction and detection of hidden)

粒子群优化算法matlab程序，简洁易懂，适用于初学者！(Particle Swarm Optimization algorithm matlab program)

说明：  用LBG算法对图像进行矢量量化，并实现了图像解码，图像解码视觉效果良好。(realized image vector quantization employed the LGB algorithm, and achieved the image decoding, image decoding visual effect is good.)

chirp信号产生比较 If you are aware of this and would still like to have a pseudo-chirp then you can take a look at the example below. I show the difference between trying to generate the type of chirp you are after and a real chirp signal. I also plot the derivative of the resulting signals, so I can highlight that between half cycles you will have a sometimes subtle (sometimes not so subtle) jump in gradient.
