This matlab code for DWT image watermarking

说明：  较为详细和全面的介绍了MATLAB在仿真系统中应用。(More detailed and comprehensive introduction to the MATLAB application in the simulation system.)

This function computes the LP guided modes of a step-index optical fiber using Matlab s "fzero" function available in the Matlab s Symbolic Toolbox. The "fzero" function uses Brent s method to find the root of a continuous function of one variable given an initial guess value.

说明：  这段代码的功能是生成高斯滤波器的，用matlab来实现的。(The code s function is to generate Gaussian filter with matlab achieved.)

this file is related to qpsk quadrature phase shift keying mod. in fading channel..which is helpful in desgining a channel with qpsk mod technique

实现滤波器的功能，从而使有噪声的图像得以修复。(Realization of the filter function, so there is noise in the image can be repaired.)

这个文章系统详细的介绍了 非线性模型的一种确定P的阶数的方法(This article describes in detail the system as a nonlinear model to determine the order of method P)
