在通信系统仿真当中,常常会使用到伪随机信号,该源代码文件中包含两类最为常用的伪随机信号gold 序列的生成和m序列的生成,程序清晰有注解(In the communications system simulation are often used pseudo-random signal, the source code file contains two types of most commonly used pseudo-random signal sequence to generate gold and m sequences generated, the program has clear notes)

matlab采用半色调技术对图像进行显示：用模板近似表示10个灰度级，每一个灰度级用3*3 的模板来表示，并对如下图所示的256*256的渐变图像进行半色调输出的检验。(matlab using halftoning image display: template approximated 10 gray levels, a gray level of each template used to represent the 3* 3, and the gradation of the image as shown in Figure 256* 256 halftone inspection of the output.)

基于虚拟力的matlab覆盖算法..虽然还有点缺陷 但完成了一大部分~~~(matlab virtual force)

Calculation of radiation pattern

对函数进行采样，经过FFT变换后，画出频谱图，估计出频率。(Sampling of the function, after the FFT transform, the spectrum drawn to estimate the frequency.)

this is a method of watermarking. where SVD and DCT both are used to get robust and secure watermarking

GPS TEC计算MATLAB代码，来自东京大学TOMOJI教授(GPS TEC calculation of MATLAB code, from the University of Tokyo professor TOMOJI)

CCITT X733规范pdf版本，内容是否详细，值得一看哦！(CCITT X733 specification pdf version of the content is detailed and worth a visit Oh!)

虹膜定位Matlab源代码，采用圆检测的方法，有友好的GUI操作界面，学习使用均方便。(iris location Matlab source code, using a round, the method of testing a friendly GUI interface. learning to use both convenience.)

离散系统的数字PID控制，可以根据S参数选择跟踪三角波、锯齿波、随机信号，跟踪效果良好。(Discrete system of digital PID control, S-parameters can be selected track triangle wave, sawtooth, random signals, track to good effect.)
