This paper has been accepted for publication at the IEEE 74th Vehicular Technology Conference (VTC2011-Fall www.ieeevtc.org/vtc2011fall ).

Abstract: The energy consumption of wideband communications receivers depends highly on the parametrization of the A/D conversion stage. The design of energy-efficient receivers requires an optimal parametrization. This paper investigates the power dissipation of state-of-the-art A/D converters and studies the optimal parametrization from an information theoretic perspective. The results show that a large sampling rate and very low quantization resolution will usually be most energy-efficient.
