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.
