{BeamSpy}: Enabling robust 60 {GHz} links under blockage

S Sur, X Zhang, P Ramanathan… - 13th USENIX symposium …, 2016 - usenix.org
Due to high directionality and small wavelengths, 60 GHz links are highly vulnerable to
human blockage. To overcome blockage, 60 GHz radios can use a phased-array antenna to …

Received power-based channel estimation for energy beamforming in multiple-antenna RF energy transfer system

KW Choi, DI Kim, MY Chung - IEEE Transactions on Signal …, 2016 - ieeexplore.ieee.org
In this paper, we propose a channel estimation algorithm based on the received power
measurements for the multi-antenna radio frequency (RF) energy transfer system. The …
