摘要
An apparatus and method for estimating velocity and Doppler frequency comprising acquiring a first plurality of time-of-arrival (TOA) measurements from a first plurality of base stations at a first time; acquiring a second and a third plurality of TOA measurements from a second and third plurality of base stations at a second time and a third time; determining a plurality of line-of-sight distance measurements using the first, second and third pluralities of TOA measurements; determining a plurality of velocity estimates and a plurality of angle of arrival (AOA) estimates, using the plurality of LOS distance measurements; determining a plurality of Doppler frequency estimates using the plurality of velocity estimates and the plurality of AOA estimates; and using a processor for determining an average Doppler frequency estimate over a plurality of sectors, wherein the first, second and third pluralities of TOA measurements are acquired over the plurality of sectors.
