| 摘 要： | 对蜂窝网中基于到达时间(TOA)/到达时间差(TDOA)的定位算法进行了分析和研究,重点介绍了Ghan定位算法在二维空间的应用.通过均方根误差(RMSE)与克拉美-罗(CRLB)下界的比较,分析了理想环境中Chan定位算法的性能.还通过实际测量,采用TOA双程测距方式得到TOA测量值,对Chan定位算法在实际测量中的性能进行了验证.实验仿真以及实际验证的结果表明算法在理想环境和实际测量中容易实现,而且定位精度相对较高.

| Abstract: | The location algorithms based on time of arrive(TOA)/time difference of arrive(TDOA) have been analyzed and compared,and Chan location algorithm in 2-dimension is mainly introduced in this paper.Through comparative analysis of root mean square error(RMSE) and Cramer-Rao Lower Bound(CRLB),the performance of Chan Location Algorithm has been discussed in the ideal environment.On this basis,the measured values of TOA have been got by Two Way Ranging mode of TOA in actual measurement,which could verify the perfo... |
