fouriertransform

Demonstrates image compression that can use in image processing

创建随机场仿真模拟，通过具体算例的程序创建随机场(random field creation)

说明：  在回归分析中，可以运用PRESS统计量来确定应选入的变量，其中，以求出的PRESS值最小为优(In the regression analysis, can be used to determine the PRESS statistic to be elected into the variables, which, in order to out a minimum PRESS value of excellent)

衰落信道仿真 function r = rayleigh( fd, fs, Ns ) r = rayleigh(fd,fs,N) A Rayleigh fading simulator based on Clarke s Model Creates a Rayleigh random process with PSD determined by the vehicle s speed. INPUTS: fd = doppler frequency set fd = v*cos(theta)/lambda v = velocity (meters per second) lambda = carrier wavelength (meters) theta = angle w/ respect to tangent (radians). fs = sample frequency (Samples per second) Ns = number of samples of the Rayleigh fading process to produce OUTPUTS: r = row vector containing Ns samples of the Rayleigh fading process Author: Matthew C. Valenti Mobile and Portable Radio Research Group Virginia Tech For Academic Use Only (Fading channel simulation)

基于matlab的雷达信号仿真分析，包含过程讲解与代码(Based on analysis of radar signal simulation matlab, including the process of explanation and code)

说明：  用matlab预测双色球的方法， 每行附详细备注介绍其目的。欢迎大家建议(Use matlab to calculate the lottery 7 digit)

已有的文本过滤受限，所以对现有的文本过滤软件进行了算法改进，对现有的问题进行分析，故而有着实用价值，但是文本过滤仍然有着不能弥补对图形图象的无效，所以有必要对图象视频等进行过滤(Already limited text filtering, so the existing text filtering software algorithms to improve on the existing analysis of the problem the club would have practical value, but still have a text filter should not make up for the graphic image is invalid, there is necessary to filter the video image)
