摘要 超宽带(UWB)技术被认为是最适合进行室内无线定位的技术,IEEE802.15.4a是IEEE第一个无线测距定位的物理层标准。为了让测距的发起者知道测距的质量,在协议中增加了品质因子(FoM),但是如何产生FoM却没有给出规定。在对接收信号能量块的统计特征进行分析的基础上提出了一种应用在超宽带无线信道中基于偏度和最大斜率联合参数的对信道品质因子进行估计的方法。仿真发现,使用该方法可以为精确的测距定位提供参考,在CM1(Channel Model)信道下可以提高30%左右的定位精度。 UWB （Uhra-WideBand） technology is considered to be the most suitable for indoor wireless location and IEEE802.15.4a is the first radio ranging and positioning physical layer IEEE standard. In order to let the sender know the quality of the ranging, FoM （ Figure of Merit） is added in this protocol, but how to produce FoM is not given. On the basis of analyzing the statistical characteristics of the received signal energy block, a method based on the joint parameters of skewness and the maximum slope was proposed to estimate the FoM in UWB radio channel. The simulation finds that this method can provide reference for accurate ranging and positioning, and can improve the ranging accuracy about 30% in the CM1 （Channel Model） channel.
