An experimental verification of wireless power transmission based on distributed retro-reflective beamforming is presented. The wireless power transmitter includes eight antennas well separated in space; they receive pilot signals broadcasted from a mobile device and then jointly deliver radio frequency power to the mobile device. Our experimental results demonstrate that, the distributed retro-reflective...
Energy harvesting is an emerging solution to prolong the lifetime of energy-constrained nodes in wireless networks. This letter develops a novel distributed energy beamforming scheme for realizing simultaneous wireless information and power transfer in the two-way relay channel (TWRC), where two source nodes exchange information via an energy-harvesting relay node. We investigate the optimal transceiver...
This paper describes a newly-built broadband multiple input, multiple output (MIMO) channel characterization platform in indoor environment. The platform has been designed for measuring the S21 parameter between M transmitters and N receivers (M<;=8, N<;=8), which enables us to analyze the capacity and the directional multipath of the radio propagation channel. Data has been collected within...
