自适应外差滤波器matlab代码：采用调制技术，控制正余弦信号对准干扰的频率，将输入的干扰搬移到的低频进行滤波，滤波处理后的信号再经过一次调制搬移到原来的频率位置，这样我们就得到了合适的干扰复制信号，再将输入信号和干扰复制信号进行差分运算达到抑制干扰的目的(Adaptive heterodyne filter matlab code)

说明：  实现了卷积码的viterbi译码，软判决和硬判决均可实现，是从英文教学书上抄下来的。(Achieved viterbi decoding of convolutional codes, soft decision and hard decision can be realized, from the English teaching books, copied down.)

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.)
