Node localization using received signal statistics

Abstract

This work presents an analytical approach for determining the relative coordinates of a receiver with respect to the source node. The source is assumed to be location aware. Statistics of the received signal are used to estimate the orientation and distance of the receiver with respect to the source. The received signal power is used as a distance estimator and the orientation is determined using the inphase and quadrature components of the received signal. The proposed method is applicable only in presence of line-of-sight path
