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.
