matlab-使用移位寄存器生成m序列（CDMA系统）(matlab-use shift register to generate m sequence (CDMA systems))

用matlab仿真滤波器，fs=1.ws=0.2,wp=0.3(Filter simulation using matlab, fs = 1.ws = 0.2, wp = 0.3)

image aliasing matlab code

在matlab的GUI界面中实现tab标签的切换功能(Implemented in the matlab interface features tab label.)

maple的入门级教程，maple的计算相比matlab更加简单也更容易上手(The entry-level tutorial maple, maple computing matlab simpler and easier to use compared to)

Channel estimator with SFBC

说明：  在二维图像上加噪声，有加白噪声或椒盐噪声，简单小程序。仅供个人参考。如果你是刚接触matlab的请下载改程序。如果你已经接触很久matlab了，就不要下载了以免浪费你的资源分。 (Plus noise at the two-dimensional image, with added white noise or impulse noise, simple little program. For personal reference. If you are new to matlab please download the reform process. If you have access to matlab a long time, do not download so as not to waste your resources in minutes.)

利用STFT可以估计信号在每片短时窗内的频率得到信号的瞬时频率，该曲线由一组时间和频率相对应的点组成，反映了信号频率随时间的变化。(Using STFT can estimate the frequency of the signal in every piece of short-time window get signal instantaneous frequency, the curve consists of a set of time and frequency of corresponding points, reflects the signal frequency changes over time. )

三维有限差分算法，使用matlab编程，可以进行数值模拟(3-D FDTD code with PEC boundaries)

说明：  利用混和同余法编写的白噪声程序 Matlab开发环境(I use the same mixture prepared by the Law white noise process development environment Matlab)
