A LOW-COST EFFECTIVE UWB LOCATION SYSTEM BASED ON FREQUENCY SYNTHESIS TECHNOLOGY

Abstract

Wireless location system based on UWB signals has been widely utilized by wireless network recently, especially for the indoor scenarios where GPS signal has been heavily attenuated. However, due to the requirement of ultra wideband signals, existing location system usually faces problems including complexity, robust and cost, which limit the potential applications. In this study, we propose a new approach to achieve ultra wideband signal through frequency synthesis. The system will send series of narrow band signals and utilize signal processing algorithm in the receiver to obtain an effective ultra wideband signal but with significantly decreased complexity and cost. The simulation results validate the proposed approach, which may lead to the novel low cost RTLS system for wireless network.
