Abstract

Official abstract text for this publication.

The invention relates to an apparatus and method for estimating the distance between a transmitter and a receiver. A method comprising obtaining a signal from a receiver; determining whether the signal more likely propagated through a line-of-sight (LOS) radio channel or a non lme-of-sight (NLOS) radio channel; using a model including parameters selected according to the radio channel to estimate the distance between the receiver and a transmitter which sent the signal.

First claim

Opening claim text (preview).

What is claimed is: 1. A method comprising: obtaining a signal from antenna elements of a multi-antenna receiver; and determining whether the signal is more likely associated with propagation from a transmitter via a line-of-sight (LOS) radio channel or a non-line-of-sight (NLOS) radio channel by performing one or more selected from the group comprising: (1) determining the angular power spectrum of the signal and comparing the angular power spectrum of the signal with known an…
