PROCEDURE FOR THE DETERMINATION OF THE POSITION FUSIONING THE INFORMATION OF THE POWER LEVELS AND THE TEMPORARY DELAY OF PROPAGATION OF THE RECEIVED SIGNALS.

摘要

Procedure for determining the position by merging the information of the power levels and the time delay of propagation of the received signals. The invention relates to a method for estimating the position of a mobile device that is part of a wireless network, using the level of power received and / or the propagation delay of the signals transmitted between the device to be located and certain network nodes with fixed and known positions called beacons. The procedure adaptively models the main sources of error in estimating the position of the mobile device in complex environments, which are multipath propagation and lack of direct vision between devices. In the estimation of the position, its evolution over time is considered and all the information collected so far is used through the use of a recursive estimation process.
