This MATLAB M-file implements a finite-difference time-domain solution of Maxwell s curl equations over a one-dimensional space lattice comprised of uniform grid cells. To illustrate the algorithm, a 1-GHz sinusoidal wave propagating in a nonpermeable lossy medium (epsr=1.0, sigma=5.0e-3 S/m) is modeled. The simplified finite difference system for nonpermeable.

使用MZM实现QPSK，内含QPSK的星座图，输入输出图像，输出相位变化图，眼图(Achieve QPSK using MZM , containing QPSK constellation, input and output images, the phase diagram of output, eye diagram)

卷积码在AWGN信道下的实现 包括simulink文件与.m文件 (Convolutional Codes in AWGN channel, including the realization of documents and Simulink. M documents)

此程序包是希尔伯特变换，经验证运行正确，希望对大家有用。解压密码为cet。(This package is the Hilbert transform, certified to run correctly, in the hope that useful to everyone.)

用龙贝格法求定积分，此例的变量数为三，但整体思路是没错的。(With Romberg method for the definite integral, the number of variables in this case is three, but the overall idea is correct.)

说明：  用matlab语言实现的将图像的进行dpcm编码算法，之后进行图像重构，进行前后图像的对比。(With matlab language will be dpcm image coding algorithm, after the image reconstruction, the images before and after contrast. )

非常准确的光斑重心算法，基于matlab (Very accurate spot focus algorithm, based on Matlab)
