OFDM versus time-hopping in multiuser ultra wideband communication systems

In this paper we present a comparison between OFDM-based radios and time-hopping impulse radios for ultra wideband (UWB) communication systems operating in a multiuser scenario, with additive white Gaussian noise and multipath channels, and narrowband interference. The comparison of the two differen...

Description
Summary:In this paper we present a comparison between OFDM-based radios and time-hopping impulse radios for ultra wideband (UWB) communication systems operating in a multiuser scenario, with additive white Gaussian noise and multipath channels, and narrowband interference. The comparison of the two different schemes for generating UWB signals is based on results obtained in numerical simulations, and is intended to assist the development of emerging UWB standards.
