The frequency-hopping orthogonal frequency-division multiplexing (OFDM) proposal, known as multiband OFDM, is a strong contender for the physical layer IEEE standard for high-rate wireless personal area networks (WPANs) bused on ultra-wideband (UWB) transmission. In this paper we analyze the performance of the multiband OFDM proposal. To this end, we (a) study the channel model developed under IEEE 802.15 for UWB radio from a frequency-domain perspective suited for OFDM transmission, (b) develop and quantify the appropriate information-theoretic performance measures, (c) compare these measures with simulation results for multiband OFDM systems, and (d) consider the influence of practical, imperfect channel estimation on the performance.
