此文章先从理论上说明了OFDM系统的实质，然后构造了OFDM系统的MATLAB仿真(This article first describes the OFDM system in theory, in real terms, and then construct a MATLAB simulation of OFDM systems)

对卡尔曼滤波器的编程设计，对其性能进行了优化设计，对搞滤波器的人很有用的(Programming on the Kalman filter, its performance is optimized for people who engage in very useful filter)

说明：  该文件很好 不行你下载试一试。我不相信你的电脑不中毒(the document you download not very good try. I do not believe that your computer is not poisoning)

说明：  好东西，相空间重构matlab程序 编程学习资料(Good things, phase space reconstruction matlab programming learning materials)

改进了BIHT中的观测矩阵，实验结果证明，误差更小了(change the measurement matix,result better)

OFDM频谱分析用。编写了三种保护间隔（循环前缀，零添加，伪随机码添加）的频谱显示程序，可研究不同长度保护间隔，不同种类保护间隔对OFDM频谱的影响(OFDM spectrum analysis)

I have thoroughly study the basic of image compression techniques. From that I have selected SPIHT algorithm for my research work. I have implemented on image compression for gray images using SPIHT algorithm. Image compression is implemented using this algorithm has better result over the previous result on gray images and also improved PSNR value high but on other side low result on compression ratio.

语音信号滤波器的改进，主要是以切比雪夫滤波器为基础，对去噪功能的处理。(The improvement of speech signal filter, mainly based on chebyshev filter, handling of denoising function. )

多元变量多目标遗传算法的实际应用，例子可以正常运行。(Multivariate multi-objective genetic algorithms practical application examples can operate normally.)
