Position location using multiple carriers

使用多载波的定位

Abstract

一种确定移动设备和在至少一个多载波信号上与该移动设备通信的无线收发机之间的距离估计的方法,包括:接收至少一个多载波信号;选择来自该至少一个多载波信号的至少一个载波信号;测量来自该至少一个多载波信号的该至少一个载波信号的信号特性;以及至少部分地基于该信号特性确定移动设备与无线收发机之间的距离估计。
A method of determining a distance estimate between a mobile device and a wireless transceiver communicating with the mobile device on at least one multi-carrier signal includes: receiving at least one multi-carrier signal; selecting at least one carrier signal from the at least one multi-carrier signal; measuring a signal characteristic of the at least one carrier signal from the at least one multi-carrier signal; and determining the distance estimate between the mobile device and the wireless transceiver based at least partially upon the signal characteristic.
