MATLAB由于其强大的功能而被广泛应用于很多工程技术领域，尤其在通信和信息处理领域更有其突出地位。众所周知，在物理级的产品作出之前，先用MATLAB进行这种电子产品的输入输出以估计这种产品的性能好坏，从而可以看出什么地方需要从新设计，什么地方需要优化等来进一步提高系统的性能，因此，伴随着现代通信系统与日俱增的复杂性，这种通信系统的仿真分析也变得尤其重要。本文介绍了利用MATLAB进行正交振幅调制与解调的仿真分析，仿真结果验证了该方法的正确性和可行性。(MATLAB because of its powerful features and is widely used in many engineering fields, particularly in the field of communications and information processing more of its prominent position. As we all know, in physics class products made prior to such use MATLAB input and output of electronic products to estimate the performance of this product good or bad, so we can see where the needs of the new design, where the need for optimization to further improve system performance, therefore, accompanied by modern communications systems with ever-increasing complexity, such a communication system simulation analysis has become particularly important. This article describes the use of MATLAB to carry out quadrature amplitude modulation and demodulation of the simulation analysis, simulation results verify the correctness of the method and feasibility.)

提出了采用小波包的方法对供暖双吸式离心水泵轴承振动信号进行去噪和提取表征 相应轴承故障的频带能量 并采用 BP 神经网络进行训练和故障识别 通过 MATLAB 进行了仿真经试验验证该方法能够有效地识别出轴承故障(The wavelet package is adoptted to De-noise and extract band energy that represent bearing fault. and the BP neural network is adopting to train and recognize faults. Through MATLAB simulation, After the test validate the method, it can effectively recognize the bearing fault.)

脉冲激光器输出表达式的仿真实验，可以研究脉冲激光器的脉冲(the matlab of the out put of the pulse laser is used for the studied by the user)

这个程序是用来寻找每个图像的K近邻的，然后得到了一个权值矩阵(This program is used to find K-nearest neighbor of each image, and then get a weight matrix)

这个是一个好好用的完美挂请大家用用好不好用大家说说(PostScript(R) Printer Description (a.k.a. PPD) files are text files containing information about special features available on PostScript printers such as paper sizes, screen values and fonts available on your printer. These files are in a very specific format that can be read by software applications. The information is used when printing your document by the printer driver for decision making purposes or to invoke particular features of the printer. )

说明：  matlab 与pefprop的接口程序(matlab interface program with pefprop)

成功的模拟DBPSK误码率，而且精度特别高，值得学习的人好好借鉴一下(BER simulation of DBPSK successful, but accuracy is particularly high, it is a good reference to learn about people)
