title: Energy efficient OFDM transceiver design based on traffic tracking and adaptive                     bandwidth adjustment.
abstract: This paper proposes a novel scheme to reduce energy consumption of digital transceivers with OFDM as the modulation scheme. The energy consumption of transceivers is saved based on two key techniques: 1) adaptively tune the bandwidth and sampling rate of the OFDM signal; 2) selectively power off individual block of parallel modules in the transceiver. Performance analysis illustrate that the newly designed transceiver consumes a significantly less amount of energy as compared to the conventional transceiver.
