Abstract—A novel orthogonal transmission based receiver-end
distributed beamforming (DBF) scheme, Rx-DBF is proposed, for
information transfer without receiver feedback. It is proven to
achieve near-perfect DBF gain and is channel fading agnostic.
Exploiting the correlation in beamformed output, a sporadic
receiver feedback scheme is also introduced, which prolongs the
duration of DBF gain to aid information or power transfer. The
proposed schemes are demonstrated to be more energy efficient
compared to the closest competitive approaches in the literature
