Abstract
A system, in an active reflector device, adjusts a first amplification gain of each of a plurality of radio frequency (RF) signals received at a receiver front-end from a first equipment via a first radio path of an NLOS radio path. A first phase shift is performed on each of the plurality of RF signals with the adjusted first amplification gain. A combination of the plurality of first phase-shifted RF signals is split at a transmitter front-end. A second phase shift on each of the split first plurality of first phase-shifted RF signals is performed. A second amplification gain of each of the plurality of second phase-shifted RF signals is adjusted.
