移动最小二乘图像变形，MATLAB，打开demo2，标定关键点，再标定要变换的位置，(Moving Least Squares image distortion, MATLAB, open demo2, calibration key points, and then calibrated position to transform)

消除50Hz工频干扰数字滤波器的设计,设计思路很巧妙，程序很小很好用(Eliminate the 50Hz frequency interference digital filter design, design ideas is very clever, good program is very small)

利用MATLAB 仿真工具设计出一个QPSK仿真程序，以衡量QPSK在理想信道、高斯白噪声信道和先通过瑞利衰落信道再通过高斯信道三种方式的调制解调得到的功率谱密度、噪声曲线、星座图及误码性能,并对仿真结果进行了分析。(QPSK simulation design and Realization Based on MATLAB)

此算法是基于PN序列的经典的定时同步算法，能直接出图，望对大家有用(This algorithm is based on the classic PN sequence timing synchronization algorithms, directly out of maps, useful look on the U.S.)

一个GPS课程的全部代码，含有数据！很实用(MATLAB GPS SCRIPTS-- Charles Meertens and Doug Miller, U. Utah 3Jan95 These scripts were developed for/during a class in GPS and Active Tectonics Department of Geology and Geophysics, U. Utah, Spring, 1994 EXAMPLE RINEX Files (the only ones guaranteed to work this release) CUR10911.94N CUR10911.94O PAR10910.94N PAR10910.94O Main Program scripts: gpshora.m -- function to calculate Modified Julian Day, Homework#1 HW2.m -- Homework#2 read RINEX observation file and plot C/A code vrs. time HW3_plt.m-- Homework#3 read RINEX navigation file, plot satellite positions HW3_3dplt.m-- Same as HW3_plt.m, but 3d position plots HW4.m-- Homework#4 calculate and plot station position as function of time Functions called: calc_nav.m-- calculate satellite position calc_pos1.m-- calculate station position constants.m-- GPS constants coords.m-- convert x,y,z coordinates to lat, long, height date2j.m-- calculate MDJ eccenr.m-- calculate "E" anomally read_nav.m-- Read RINEX Nav file r)

这里是通信领域中各种基带信号（非常全，几乎最新的都有），用matlab编写，给出了相应的带宽和功率谱密度，很值得学习通信的看看(Here are the various communications baseband signal (very full, almost all the latest), written with matlab, the corresponding bandwidth and power spectral density, it is worth learning to see communication)
