Mise en place d'une couche physique pour les futurs systèmes de radiocommunications hauts débits UWB (Ultra Wide Band)

Abstract : The UWB (Ultra Wide Band) consists in transmitting signal between 3.1 and 10.6 GHz with a power limited to –41.3 dBm/MHz. For high data rate (100 to 500 Mbit/s) and short range (1 to 10 m) applications, the state of the art solutions are based on complex digital processing. Mitsubishi ITE proposes an alternative multiband (MB) impulse radio solution based on a non-coherent receiver. The OOK demodulation is done by an original energy detection with a threshold which is adapted dynamically according to propagation conditions. The complete parallelization of this MB-OOK solution allows the system to both avoid inter-symbol interference and recover virtually all available energy. Furthermore the impulsive approach limits multipath channel fading. The comparison of MB-OOK and MB-OFDM systems demonstrates the pertinence of the proposed solution for high data rates and short range applications with low power consumption.
