Localization of wireless terminals using subspace matching with ray-tracing-based simulations

This paper presents a method for localizing transmitters in a microcellular environment dominated by non-line-of-sight (NLOS) propagation, using one base station that is equipped with one antenna array. The proposed method takes advantage of the dissimilarities in multipath propagation characteristics of distinct locations in such an environment and site-specific ray tracing models to localize a transmitter. Studies of experimental data are provided to validate the proposed method.
