ofdm的一种信道估计准则：最大似然信道估计准则(ofdm channel estimation as a criterion: maximum-likelihood channel estimation criteria)

用matlab制作的模拟动画程序，内容为电梯的升降演示。(Animation produced using matlab simulation program, the content of the elevator lift demonstration.)

文件内含有在MATLAB基础上实现的PSO代码，测试过，能顺利运行，并且可以继续添加测试函数进行编译。(File contains MATLAB basis in the realization of PSO code, test, can run smoothly, and can continue to add the test function to be compiled.)

变采样和多相滤波器的实现。本程序实现了一个变采样程序，中间设计滤波器设计和插值抽取。其中滤波器设计用的是窗函数法，根据要求设计窗函数，得到窗函数的长度。接着是插值，滤波，抽取，得到最后变采样之后的波形文件、另外对比了用直接卷积和多相分解卷积两种方法最后的结果。 (Implementation of variable sampling and polyphase filter. This procedure implements a variable sampling procedures, intermediate design and interpolation and decimation filter design. The filter design is using the window function method, according to the requirements of the design of window function, get the length of the window function. Then the interpolation, filtering, extraction, and finally obtain the variable wave file, sampling after the addition of contrast and polyphase decomposition results of two methods for convolution last direct convolution.)

数字图像处理，冈萨雷斯著，一本很好的书，值得一看！而且本书为MATLAB版本，很具有参考价值。(Digital Image Processing, Gonzalez' s book, a very good book, worth a visit! And for the MATLAB version of the book, it is a reference value.)

在地震反演中需要进行流体替换的研究，流体替换中用到了gassmann方程 (Seismic inversion studies need to replace the fluid, fluid replacement used gussmannn equation)

used to extract texture feature using gabor filter

GENETIC ALGORITHM OPTIMIZATION

This example shows the use of the FFT function for spectral analysis. A common use of FFT s is to find the frequency components of a signal buried in a noisy time domain signal.

this coding is related on image processing and this code is very effectively used in detect the faces,iris and finger print for differentiate the fake and real image.the gradient ,mean square algorithm is used.
