Abstract

This paper presents the performance of ultra-wideband multi-band orthogonal frequency division multiplexing (UWB MB-OFDM) systems with extra diversity. To fully obtain diversity gain in the current MB-OFDM system when time-domain spreading (TDS) and frequency-domain spreading (FDS) are adopted, two consecutive OFDM symbols are designed to be cyclic shifted each other. Simulation results show that the MB-OFDM using additional frequency diversity outperforms conventional MB-OFDM.
