对图像进行arnold变换以实现图像之乱(great)

这个程序的功能主要是完成对输入二进制信号序列的QPSK和8PSK调制与解调。(This program is the simulation of QPSK and 8PSK modulation and demodulation.)

Function to simulate a crane and its load and strain

在无线通信中，存在着严重的多径现象，能够引起严重的ISI。判决反馈均衡器（DFE）是目前最常用的一种消除ISI的均衡器。本程序使用Matlab实现的QPSK下的DFE。(In wireless communication, there is a serious multi-path phenomenon, can cause severe ISI. Decision feedback equalizer (DFE) is the most commonly used in an equalizer to eliminate the ISI. This procedure using Matlab under QPSK realize the DFE.)

主要描述的是平面电磁波的电磁散射问题，适合搞电磁计算的科研人员等(This guide provides a brief reference to the Graphical User Interface (GUI) that implements the propagation of a TE (Transverse Electric)/TM (Transverse Magnetic) plane wave through a multilayered structure of media with different electromagnetic characteristics. The incident wave is a TE/TM plane wave in the the zy plane (sinusoidal regime with temporal convention ejωt ), traveling from+z to-z. )

讲述了机械故障诊断中一些理论知识，如现在常用的HHT，对初学者有帮助。(Tells the story of some mechanical fault diagnosis theory of knowledge, such as the now commonly used HHT, help for beginners.)

该课件包含matlab的基本知识和仿真知识，是初学者的好教材。(The courseware contains the matlab simulation of the basic knowledge and knowledge is good material for beginners.)

一个数字计数器，每100秒即输出一个脉冲信号，可用于定时控制(a digital counter, every 100 seconds is a pulse output signal can be used for timing control)

matlab2009和2010从入门到精通的好教材(matlab 2009 and 2010 from entry to the proficient good material)

this code explains the performance of BPSK and QPSK modulation techniques in terms of there bit error probability. this code plots the simulated bit error rate of bpsk and qpsk in terms of SNR. both modulation techniques are explained in RAYLEIGH fading channel.
