无线定位系统研究

Study of the wireless positioning system

介绍无线定位系统的发展状况以及在现实中几个实际的应用,及无线定位系统中几种主要的定位方法,主要讨论了根据信号传播时间定位的方法TOA,根据信号到达角度定位的方法AOA,根据信号强度的统计值定位的方法MCCPS,以及对这些基本算法的改进,并说明了每种算法的优点和缺点.接着介绍了影响定位准确性的因素,最后做出总结并指出未来工作的方向.

This paper gives some example of wireless positioning system, and presents some positioning techniques. We mainly introduce positioning technique based on the distance named TOA, and a based on the angle named AOA, and a based on statistics of the signal strength named MCCPS and some amelioration about these elemental techniques, and we point out the advantages and defects of each technique. This paper also discusses the factors that influence the accuracy of positioning. Finally, we give a summary and point out the direction of our future work.
