摘要

超宽带(UWB)通信系统由于具有较高的多径分辨率，可提供高精度的定位估计。本文研究了利用脉冲无线电(IR)传输中定义的脉冲序列估计到达时间(TOA)的归一化最小方差(NMV)技术。定位估计是通过扩展卡尔曼滤波(EKF)和TOA偏差跟踪来解决的，即使在非视线(NLOS)场景下也能实现高精度。

High resolution location in ultra wideband communications systems

Ultra wideband (UWB) communications systems provide high accuracy positioning estimation because the high multipath resolution capacity. This paper deals with the normalized minimum variance (NMV) technique for estimating time of arrival (TOA) exploiting the pulse train defined in the Impulse Radio (IR) transmission. Positioning estimation is tackled with the extended Kalman filter (EKF) with TOA bias tracking allowing high accuracy even in non line of sight (NLOS) scenarios.
