matlab计算GPS周跳程序，内容丰富，可观性极强(GPS Cycle-slip calculation and detection program, is very good for related researcher and user)

《大数据时代》是国外大数据研究的先河之作，本书作者维克托·迈尔·舍恩伯格被誉为“大数据商业应用第一人”，拥有在哈佛大学、牛津大学、耶鲁大学和新加坡国立大学等多个互联网研究重镇任教的经历，早在2010年就在《经济学人》上发布了长达14页对大数据应用的前瞻性研究。(" Big Data era" is the first of its kind for large data studies abroad, Victor Meyer Schonberg known as the author of the book " Big Data business applications first person" , with at Harvard University, Oxford University, Yale University and a number of Internet research center such as the National University of Singapore, teaching experience, as early as 2010 in " The Economist" published up to 14 pages on a prospective study of a large data applications.)

该程序基于MATLAB平台编写，实现了GPS/INS基于位置松组合的卡拉曼滤波算法，分为两部分，GPS_INS.m为组合算法主文件，输入捷联惯导平台实测数据，设置各量测噪声参数，在调用卡尔曼滤波函数进行数据融合校正，最后实现绘图功能；kalman_GPS_INS.m 为卡拉曼滤波程序，输入量测误差以及各噪声参数可得位置和速度估计值。(The program is based on MATLAB platform, and realizes the Kalman filtering algorithm of GPS/INS based on position loosening combination. It is divided into two parts. GPS_INS.m is the main file of the combined algorithm, inputs the measured data of the strapdown inertial navigation platform, sets the measurement noise parameters, and carries out data fusion correction by calling the Kalman filter function, and finally realizes the drawing. Function; kalman_GPS_INS.m is Kalman filter program, input measurement error and noise parameters can be estimated position and velocity.)

This is ieee paper describes OFDM radar implementation, good for study and understanding
