This is matlab code for estimating the static linear system with Ridge Regression that is written by matlab 7.0. Here we want to estimate the below function: 1 - u^2 + 2*u^3 +u^5 +3*u^7 these are 2 files : without noise and with noise finally,there are plots for showing results.

说明：  采用hog+SVM对路标进行识别，先训练再测试，准确率达到百分之九十四左右。(Hog +SVM is adopted to identify road signs, which is trained first and then tested, with an accuracy rate of about 94 percent.)

实现两个序列的循环卷积，输出卷积后的序列结果(Implement circular convolution of two sequences, the results of the output sequence after convolution)

基于MATLAB的直扩信号的产生，扩频，调制解调以及解扩(matlab dsss )

说明：  语音信号处理代码，可插入水印，并进行还原处理(Speech Signal Processing Code)

自适应滤波算法（最小均方误差算法）matlab源码程序。(Adaptive filtering algorithm matlab source program。)

PID控制器的源码设计，一个比较简答易学的程序代码(PID controller source design, a relatively short answer to learn of the program code)

这是一个基于空时分组编码的MIMO_OFDM通信系统的仿真设计。 此系统包括QPSK调制解调，IFFT调制，空时编解码，基于训练符号的信道估计等通信模块。 ( This is a space-time block coding based on the MIMO_OFDM Communication System Simulation and Design. This system consists of QPSK modulation and demodulation, IFFT modulation, space-time coding and decoding, based on training symbols such as communication channel estimation module.)
