A Multi-Carrier Technique for Precision Geolocation for Indoor/Multipath Environments

D. Cyganski, J. Orr, W.R. Michalson

Abstract:	A novel means for precise and multipath-compatible geolocation is introduced in this paper. By applying a matrix decomposition-based multi-carrier range recovery algorithm, super-resolution location solutions can be obtained for one or more signal sources in a severe multipath environment. The technique allows separation of true source signals from multipath reflections without resort to impulsive, wideband signals. The proposed precision location signal structure is easily adapted to conform to spectral allocations and is compatible with simultaneous use for COFDM based communication. The technique is well suited for deployment as a system for precision relative location of ad hoc transceivers with respect to one another. A proof-of-concept system was constructed and experimental results are discussed.
