Signal processing approach towards designing ultra-low power transceivers

This work explores the design of such ultra-low power transceivers from a signal processing approach. We propose an ultra-low power wake-up radio, which is always turned on and is used to detect the beacon signal coming from the access network, and to subsequently enable the rest of the transceiver. However, such low-power radios suffer from poor sensitivity. The objective of this paper is to use efficient signal shaping techniques used in combination with ultra-low power receivers in order to achieve significant power savings.
