Ultra-Wideband Communications and Positioning

Ultra-Wideband (UWB) communications is an emerging new technology for high speed data transmission systems that is expected to enable low-cost and low-power devices. One of the most appealing variants of UWB is Impulse Radio, where, instead of a modulated carrier, streams of ultra-short pulses (<< 1 ns) are used for wireless data transmission, resulting in signals of huge bandwidths (>> 1 GHz) but at very low power spectral densities. In principle, the nature of the signal used makes the technology suitable for low-cost implementations in standard CMOS technology. However, before UWB systems can be produced at large scale and low cost, there are numerous open research issues to be solved. In this research activity, we investigate signal processing, system and channel modeling, and system architecture design, with applications in communications and positioning.
