Kalman_filtering_MATLAB

本程序设计了常用的几个坐标系的转换，从WGS—84与PZ－90坐标系的相互转换，以及空间直角坐标系与大地坐标系的转换。(This procedure has designed a number of commonly used coordinate system conversion from WGS-84 and PZ-90 coordinate system conversion, as well as the spatial Cartesian coordinate system and geodetic coordinate system conversion.)

说明：  数字通信中，对面对判决环和非面对判决环的相位估计的仿真，调制方式采用QPAK调制方式。(Digital communication for non-face to face judgment ring and phase estimation of judgment ring simulation, modulation using QPAK modulation.)

粒子群算法之一，可在matlab中运行，分析一些函数的最优化问题(a kind of particle swarm, can be used in matlab)

This is matlab model for ASK modulation techniques.

本程序完成cic滤波器的设计，并且含有滤波实例，同时设计了三种cic滤波器进行比较(this programm propose the design of cic filter. it contain an example of how this filter works. meanwhile it compares three different cic filter)
