Multi-band Impulse Radio - An Alternative Physical Layer for High Data Rate UWB Communication

This article overviews current research results within the UKoLoS sub-project MIRA (Physical Layer Optimization for a Multi-band Impulse Radio UWB Architecture). A multi-band impulse radio UWB system operating in the frequency range between 3.1 GHz to 10.6 GHz is presented. To highlight its potential to be a suitable, alternative solution for future low complexity, power efficient and high data rate wireless communication over short distances, two aspects are pointed out. The first aspect concentrates on optimized multilevel pulse amplitude modulation, enabling higher data rates and flexible frequency usage. The second one deals with various approaches aiming at an efficient broad- or narrow-band interference handling.
