说明：  用小波和小波包对太阳黑子数据进行降噪处理(Using wavelet and wavelet packet noise reduction processing on the sunspot data)

主要讲述jeason反演软件的主要流程，对要学习反演的地震解释人员很有用，希望大家多看看(Main main about jeason inversion software process to study the inversion of the seismic interpretation staff was very useful, hope we see more)

i wanna to find the error in this code

包含了各种matlab数字图像处理的小程序 (Contains a variety of digital image processing matlab applet)

pi/4-dqpsk 调制解调 的 matlab 仿真，通过srrc滤波器实现16倍的上采样(pi/4-dqpsk modulation and demodulation matlab simulation, through srrc filter to achieve 16 times the sampling)

利用matlab实现glomb编码算法，实现了数据的压缩(Coding algorithm using matlab to achieve glomb)

Implementation of an algorithm to recognize faces using PCA

1. BPSK modulation of data which ever you input (default data is “MANIPAL REDDY”). 2. MANIPAL REDDY is changed into ASCII Format and into two-bit format for BPSK Modulation. 3. Chaos is used for spreading the binary bit sequence. 4. Uniformly distributed Noise is added to Spread signal. 5. After reception Chaotic Chip sequence is used to recover message . 6. Filter is used for removing spikes and noise. 7. Note the filter is used is just for showing a little realisitic picture. 8. Appropriate filter should be used. 9. The original data in binary and recovered data in binary format are compared

基于干扰观测器的pid控制，非线性pid鲁棒控制，线性pid控制器设计(Disturbance observer based PID control, nonlinear PID robust control, linear PID controller design)

说明：  GPS接收机方面的MATLAB程序，有很多gps接收机实现时所用到的函数，很很好的参考，快速掌握GPS接收机实现方法(GPS receiver' s MATLAB program, there are many gps receiver when used to achieve the function, it is a good reference, to grasp the realization GPS Receiver)
