LANDMARC系统定位算法实现与仿真优化

摘要

介绍在室内定位系统中广泛使用的LANDMARC算法，分析其基本原理，并描述其在MATLAB中的仿真实现。提出一种基于能量等级数的优化方法，以减小算法误差，提高定位精度。分析仿真结果表明，在其它因素不变的情况下，通过增加能量等级数能够有效提高定位精度。%The algorithm of LANDMARC is introduced in this paper ,which widely used in indoor positioning system . Then the basic principle of the algorithm is analyzed and the simulation process in MATLAB is given .An optimization method based on the number of energy level was put forward to minimize the error and improve the accuracy of positio-ning .Simulation results show that by increasing the number of energy level ,the positioning accuracy can be improved in the case of other factors unchanged .
