New Energy-Saving Multicarrier Transceivers and Their Standardization

This letter describes how the energy efficiency of base stations used in mobile communications can be improved by replacing state-of-the-art single carrier transceivers with novel multicarrier transceivers that suppress the need for lossy combiner stages. In the particular case of the Global System for Mobile Communications (GSM) radio access technology, we show how standards may be adapted to enable the feasibility of such multicarrier architectures.
