Performance Comparison on Three Kinds of Transmitted-reference Ultra-Wideband(UWB) Systems

Tiefeng Li

Abstract

In this paper, three kinds of transmitted-reference Ultra-Wideband(UWB) system are presented, including transmitted reference Ultra-Wideband (TR-UWB) Radio, slightly frequency-shifted reference Ultra-Wideband (FSR-UWB) Radio and Code-Orthogonalized Transmitted-Reference Ultra-Wideband(COTR-UWB) Radio.Then introduce the signal models and receivers of three schemes are given .Finally, this paper describes the simulation on BER performance of the schemes by using IEEE802.15.4a office NLOS channel model, and the result shows that TR-UWB system is the best BER performance while COTR-UWB system more attractive.
