智能控制课本中的一些程序，其中有一章节是自己写的(some .m about control)

THIS is very good documens for better optimization and giving better result option

这是一个好用的频偏估计算法的matlab仿真程序,LDPC码的完整的编译码，FIR 底通和带通滤波器和IIR 底通和带通滤波器。( This is a useful frequency estimation algorithm matlab simulation program, Complete codec LDPC code, Bottom-pass and band-pass FIR and IIR filter bottom pass and band-pass filter.)

用MATLAB仿真GPS卫星运动，仿真GPS卫星的可见性(Simulation of GPS satellite motion with MATLAB,Visibility of simulated GPS satellites)

说明：  system identification continued

双谱分析获取信号成分，PCA获取信号主成分，剔除无用成分(PCA extracted bispectrum principal component, data compression, signal acquisition signal independent components, principal component.)

一种基于红外图像分层处理及动态压缩的 DDE 算法。该算法先将原始14bits 红外图像数据信息中的大动态低频背景和小动态高频细节进行分离提取，并分别对提取的细节层和背景层进行相应的灰度增强和灰度抑制处理，再调整和压缩各图层的动态范围并最终合成 8bits图 像。实验结果表明，该算法能较好地保留并突出原始红外图像中的边缘和细节信息，达到了预期设计的目标。 (put forward a DDE algorithm based on hierarchical processing and dynamic compression of infrared image． At first，this algorithm dissociates the background ( with wide dynamic and low frequency) and the detail ( with narrow dynamic and high frequency) in the data information ( 14 bits) of original infrared image，and pick up them respectively． Then，it enhances the gray of details layer and restrains the gray of background layer，and readjusts and compresses dynamic range of each layer． Finally，it composites output image ( 8 bits) ． The experimental results show that the proposed algorithm can retain detail information and edges in original infrared image and carry the purpose of design． )

说明：  随机共振是一种新颖的信号降噪方法，适量的噪声能够共振出隐含的特征频率。(SR is a good method to denoise signals.)
