基于3G标准wcdma的上下行通信链路，基于3GPP协议，采用matlab simulink的仿真(Up and down based on 3G standards wcdma line communication link, based on 3GPP protocol, using matlab simulink simulation)

用matlab编写的遗传算法加上粒子群算法，求解最优配置问题的程序(Prepared by the genetic algorithm with matlab with PSO, the optimal configuration problem solving process)

particle swarm optimization passive cognition

这个程序是为了区分SIGNAL和VARIABLE在不同情况下要怎样使用的例程，程序中使用了三种情况来说明问题(This program is designed to differentiate between routine SIGNAL VARIABLE in different situations and how you want to use, the program uses the three cases to illustrate the problem )

图像变换及频域滤波 编写快速傅立叶变换算法程序，验证二维傅立叶变换的平移性和旋转不变性(The image transformation frequency domain filtering writing Fast Fourier Transform algorithm procedures to verify that the two-dimensional Fourier transform of the translational and rotational invariance)

利用SVM做回归线性测试。对于大盘指数的有效预测可以从整体上观测股市的变化提供强有力的信息，所以对上证指数的预测很有意义。通过对上证指数从1990.12.20-2009.08.19每日的开盘数进行回归分析，最终拟合的结果是：均方误差MSE=2.35705 e-005，平方相关系数 R=99.9195 。SVM的拟合结果还是比较理想的。(Make use of SVM linear regression testing. For the market index can predict the observed changes in the stock market as a whole to provide a strong information, so it makes sense to predict the Shanghai index. Through the Shanghai Composite Index opened daily from 1990.12.20-2009.08.19 number of regression analysis, the results of the final fit are: mean square error MSE = 2.35705 e-005, the square of the correlation coefficient R = 99.9195 . SVM fitting result is quite satisfactory.)
