Abstract:
Device, method and computer program to make better use of measurements of received signals for determining location are provided. A client device is configured to receive a signal that contains a reference symbol modulated onto a plurality of subcarriers. The client device determines a plurality of weights based on the reference symbol and line-of-sight channel frequency responses for the subcarriers, so that each of the plurality of weights is associated with one of the subcarriers. The client device determines a gain associated with the received signal using the plurality of weights. A network device may receive from the client device information indicative of gains, wherein a gain indicates a signal strength at which the client device was able to receive a respective signal. The location of the client device may be determined by using information about network device locations, transmission directions, and the gains.
