本文介绍的是一种改进的SPIHT算法，是基于图像编码的小波系数块的，它主要是把四个系数分成一个块，与阈值比较，分出重要与非重要，在进行编码。(This article is a modified SPIHT algorithm is based on the wavelet coefficients of image coding block, it is mainly divided into the four coefficients of a block, compared with the threshold value, separate the important and non important, during the encoding.)

Matlab源程序，是对DTMF进行调解和解调的程序。(matlab source for modernization of DTMF)

小波消噪算法我用的小波消噪算法我用的小波消噪算法我用的(Wavelet denoising method I use)

describe how to generate OFDM signal,but do not add interval

PSCAD程序与MATLAB程序的接口，将PSCAD文件产生的.out文件自动处理到所需matlab的文件格式(PSCAD program interface with MATLAB program ， .out file generated by PSCAD automatically processed to the required file format for matlab)

说明：  包含两个MATLAB程序，具体内容见里面的txt文档，第一个程序近似算法结果很差(Contains two MATLAB program details see the inside of the txt document, the first result of poor process approximation algorithm)

自己做的研究生招生系统，增加了学校之间的比较功能，图标显示，分数线预测等(Own graduate admissions system, increases the comparison function between schools, icons, score prediction)

代码实现了基于卡尔曼滤波算法的信号估计，该算法有很好的跟踪能力，能用于信道事变的情况(Code based on the Kalman filter algorithm estimates the signal, the algorithm has good tracking ability can be used in case of channel events)

采用独立PD控制，满足二关节机械手定点控制的要求。(Independent PD control, to meet the requirements of the robot sentinel control.)
