A robust front-end architecture for low-power UWB radio transceivers

Abstract

In this paper, we propose a transceiver architecture and a novel modulation scheme for ultra-wideband (UWB) radio technology. The modulation uses a combination of binary-shift keying and a carrierless amplitude modulation. A demodulation method is proposed and theoretically investigated. These techniques enable the implementation of low-power although robust and reliable UWB radio transceivers intended for short ranges (below 10 m) and medium bit rates (1-10 Mb/s). This paper addresses the theoretical bit error rate performance of a demodulator/detector for data transmission over an additive white Gaussian noise channel. Additional simulation results are given to assess the performance of the proposed solution in a dense multipath environment with the help of available UWB channel models. © 2006 IEEE.
