这是我们学习阵列时用到的程序，有方向图程序，谱程序以及其他程序。其中包括不同阵列结构，有线阵，圆阵。(This is programs when we learn array 。)

MIMO系统的各种空时分组码仿真 包括2*2 alamouti编码，1/2速率的空时分组码(MIMO system simulation of space-time block codes, including 2* 2 alamouti coding, 1/2 the rate of space-time block codes)

the best model of a scorbot with 6 dof

ESPRIT_MATLAB，适用于DOA估计，程序简单易懂，非常适合于刚入门的同学(ESPRIT Algorithm)

The aim of this application is to implement scalable mpeg type compression by varying DCT coefficients and finding minimum number of DCT coefficients that can give minimum acceptable quality.. This application only works for gray scale.

修改后的phase函数，把它的门限值换为pi，使用更方便(The modified phase function, the threshold for it to pi, the use of more convenient)

Allan Variance calculation with ability of exponentially increasing step (MatLab function)

，用MATLAB实现快跳频通信系统的仿真。主要应用了SIMULINK和COMMUNICATION BLOCKETS两个模块。整个设计包括了信源产生部分、发送部分、跳频调制部分、信道部分、接收部分和结果分析部分共六个模块，核心技术是伪随机序列的产生和频率合成器的设计，而关键技术是收发两端的伪随机码元的同步。伪随机码的产生用S－函数编程来开发自己的SIMULINK模块。同步的实现是收发两端采用相同的扩频脉冲触发。而且在设计中每个模块都采用了模块封装技术，从而简化了框图结构(Using MATLAB to achieve fast frequency-hopping communication system simulation. The main use of SIMULINK and COMMUNICATION BLOCKETS two modules. The whole design, including part of the generated source, sending part of some frequency-hopping modulation, channel of the receiving part and the results of analysis of part of a total of six modules, the core technology is the emergence of pseudo-random sequence and frequency synthesizer design, and the key technology is the transceivers at both ends of the pseudo-random synchronization symbol. Pseudo-random code generated by S-function programming to develop their own modules SIMULINK. Synchronization is used to send and receive ends of the same spread-spectrum pulse trigger. But also in the design of each module using the module packaging technology, which simplifies the structure of the diagram)
