Abstract

In this paper, we present the "subspace matching localization" as a technique for localizing non-cooperative 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 the multipath propagation characteristics of distinct locations in such an environment and site-specific ray tracing models to localize a transmitter. Issues regarding the coherency/or non-coherency of multipath signals and effects of spatial smoothing on subspace matching localization are also addressed.
