cosin wavelet transform code using matlab

take a input vector which is no of users of b[kx1] and code vector which will be a matrix now s=[Nxk],where then give to matched filter,non-correlating detector, by randomised sequence.

this is the research doc for mp3 stegnography

说明：  此程序通过采样产生了一个非常标准的BPSK信号，是理解通信原理数字调制的好帮手(his procedure generated by sampling a very standard BPSK signal, digital modulation is to understand the principles of good communication assistant)

FDTD 2d with PML

matlab程序用于计算光镊中的轴向力，开发者使用高超的matlab编程能力，是程序简洁易懂(matlab source program for calculating opitcal trap force.Programmer made use of his higher lever ability to create a simplified and easy to understand progfram. )

说明：  利用该程序可实现插值运算，达到差值滤波，CI插值滤波器的实现(cascador integrator comb fliter s design)

Very effective Audio AGC

matlab的小波工具箱入门，包括调用 wfilters 来获得指定小波的分解和综合滤波器系数，直接调用Wname 可指定为列表中的任意一种小波，查看具体小波的信息，获得一个标准的正交变换/双正交变换 的尺度和小波函数（数字近似值），等等。
