Perspectives Offertes par la Radio Impulsionelle Ultra-Large Bande pour les Communications Sans-Fil à Courte Portée et Faible Consommation

Abstract : Due to the gated nature of ultra-wideband impulse radio communications, it appears that the higher the data rate is, the more energy-efficient IR-UWB emitters and receivers are. Thus, impulse radio is intrinsically well-suited for short range applications when high data rate are required. However, many applications require low data rate until some bytes per second or less, integration of power-saving techniques becomes essential for impulse radio. These techniques indeed allows the static part of the power consumption to be drastically reduced and then to achieve an energy efficiency for every bit rate closed to its maximum normally obtained at high bit rate only. To do this, some design strategies for emitters and power management schemes for receivers are proposed and their efficiency is demonstrated on existing circuits.
