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

System performance aspects of the Multi-carrier Ultrawideband (MC-UWB) approach to positioning are presented. 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 was introduced in a previous paper. This paper presents the analysis of system performance as a function of the major parameters, including bandwidth, frequency component spectral spacing, transmitted signal power, and range. These results facilitate the design of MC-UWB positioning systems for specific environments.
