Time Hopping QPSK Impulse Signal Transmission for Ultra Wideband Communication System in the Presence of Multipath Channel

Chaiyaporn Khemapatapan, Watit Benjapolakul, Kenji Araki

Abstract

New ultra wideband (UWB) communication system using quadrature-phase shift keying (QPSK) impulse modulation with time-hopping (TH) multiple-access scheme is proposed. The simulation results in multipath channel show that the proposed UWB communication system can provide better performances compared with conventional TH-PPM UWB communication system.
