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)

说明：  这个程序主要用于matlab的一个函数的用于误差分析，是针对一个特定函数而编写的(This procedure is mainly used for a function matlab error analysis, is written for a specific function of)

信号处理中的旋转不变子空间法，BP神经网络用于函数拟合与模式识别，调试通过可以使用，DC-DC部分采用定功率单环控制，在MATLAB中求图像纹理特征，毕业设计有用。( Signal Processing ESPRIT method, BP neural network function fitting and pattern recognition, Debugging can be used, DC-DC power single-part set-loop control, In the MATLAB image texture feature, Graduation usefu.)

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)
