A Novel Mode Switching Scheme Utilizing Random Beamforming for Opportunistic Energy Harvesting

Since radio signals carry both energy and information simultaneously, a unified study on Simultaneous Wireless Information and Power Transfer (SWIPT) has recently attracted a great deal of attention for providing wireless energy to communication devices. This paper proposes a novel receiver mode switching scheme for SWIPT and the enabling transmitter design for a point-to-point Multiple-Input Single-Output (MISO) channel when the Channel State Information (CSI) is not available at the transmitter. The proposed scheme employs random beamforming at the transmitter to generate artificial channel fading to enable opportunistic energy harvesting at the receiver when the channel power exceeds a certain threshold.
