摘要
文中讨论了定位估计采用的几种算法-LSE(Least Square Error)、APIT及Taylor算法,并提出新的算法,即将APIT和Taylor结合起来进行协同定位的方法。将几种算法运用于超宽带定位中,并讨论平均定位误差与噪声方差、参考节点数及定位失败率等之间的关系,对APIT、Taylor及两者的协同算法的累计分布函数(CDF)进行了仿真。
This paper discusses the algorithms which are normally used in the location methods-LSE ( Last Square Error), APIT and Taylor. A new method of cooperating APIT with Taylor for location is put forward. The relationship between the average error of location and the variance of noise and that between the number of reference nodes and fail rate of positioning are discussed. CDF of APIT, Taylor and the cooperated methods is simulated.
