图像直方图的绘制，此程序提供两种方法，一是利用matlab自带得工具箱绘制，另一种是利用统计学的方法编程实现，最后对两种方法进行比较(Image histogram drawing, this program provides two methods, one using matlab toolbox comes too draw, another is the use of statistical methods to program implementation, and finally to compare the two methods)

说明：  设计一个有干扰的直接序列扩频通信系统， PN码由m序列产生器产生，经过高斯白噪声信道。在接收端接收到的信号包括“有用信号+高斯白噪声+干扰”，将接收信号进行解扩，判决，得到用户的信号检测结果，绘制不同的扩频增益（增益值为10，30，50）下，误比特率随信噪比Eb/N0的变化曲线。(Design of a direct sequence spread spectrum interference system, PN code generated by the m sequence generator, after white Gaussian noise channel. Receives the signal at the receiver, including &quot useful signal+ Gaussian white noise+ interference&quot , will receive the signal despreading, judgments, get the user' s signal test results, draw a different spreading gain (gain value of 10,30, 50), the BER curves with the signal to noise ratio Eb/N0.)

基于数控机床进给系统PID参数优化程序SOA。(Feed System Based on SOA PID parameter optimization program CNC machine tools.)

wireless sensor networks are required to share one wireless channel among several sensor nodes. An efficient media access control (MAC) protocol must be developed and implemented on hardware. This MAC must be easily used by future users on the target hardware. The MAC should avoid data collision and posses strong speed of transmission.

说明：  Matlab入门级图像处理程序__运用5种不同的梯度增强法进行图像锐化(Matlab image processing procedures for the entry-level __ gradient using 5 different methods for image enhancement sharpening)

为了克服用硬件电路实现混沌信号的困难，本文采用MATLAB/Simulink 软件对蔡氏电路进行仿真研究。实验结果 表明，蔡氏电路结构简单，具有极其丰富的动力学行为，提高了通信的安全(In order to overcome the chaotic signal with a hardware circuit difficulties, we use MATLAB/Simulink software simulation of Chua' s circuit. Experimental results show that the Chua' s circuit structure is simple, extremely rich in dynamics, to improve the security of communications)
