Wireless networks can be self-sustaining by harvesting energy from ambient radio-
frequency (RF) signals. Recently, researchers have made progress on designing efficient …

Far-field microwave power transfer (MPT) will free wireless sensors and other mobile
devices from the constraints imposed by finite battery capacities. Integrating MPT with …

In energy harvesting communications, users transmit messages using energy harvested
from nature during the course of communication. With an optimum transmit policy, the …

In this letter, we consider a large-scale multiple-input multiple-output (MIMO) system where
the receiver should harvest energy from the transmitter by wireless power transfer to support …
