Performance Limitations of a Precision Indoor Positioning System Using a Multi-Carrier Approach

David Cyganski, John Orr, Ryan Angilly and Benjamin Woodacre

Abstract:	The spatial resolution limits of the Multi-carrier Ultrawideband (MC-UWB) approach to positioning are presented. This paper directly and quantitatively addresses the underlying causes of performance degradation and system failure in the presence of multipath signals. While the results have been obtained in the context of the MC-UWB system, the predicted performance should be applicable to other signal structures with equivalent bandwidth and SNR. This system implements a wideband or ultrawideband ranging signal in the frequency domain, retaining the frequency coordination and spectral allocation benefits of conventional systems while including signal characteristics which permit resolution of multipath signals in indoor or other difficult RF propagation environments. The overall system architecture and other aspects of system performance analysis were presented in previous papers.
