Abstract

In this paper, we propose a time interleave (TI)-ultra wideband (UWB)-impulse radio (IR) system where Nf monocycle pulses per information symbol are transmitted not continuously but discontinuously through the time interleaver to get more time diversity. Moreover, we compare the diversity gains of the UWB-IR systems on block fading channels with the fading block size q: the UWB-IR system with a single transmit antenna, the space time (ST)-UWB-IR system with Nt transmit antennas, and the TI-UWB-IR system with a single transmit antenna. Simulation results show that when the number of transmit antennas Nt is larger than or equal to the fading block size q, all the systems can achieve the same diversity gain. When the number of transmit antennas Nt is smaller than the fading block size q, the TI-UWB-IR system can achieve the largest diversity gain, and the ST-UWB-IR system and the UWB-IR system follow in order.
