Ahmed Bader (Inventor), Mohamed-Slim Alouini (Inventor)

Research output: Patent


An embodiment of a non-invasive beamforming add-on apparatus couples to an existing antenna port and rectifies the beam azimuth in the upstream and downstream directions. The apparatus comprises input circuitry that is configured to receive one or more signals from a neighboring node of the linear wireless sensor network; first amplifier circuitry configured to adjust an amplitude of a respective received signal in accordance with a weighting coefficient and invoke a desired phase to a carrier frequency of the received signal thereby forming a first amplified signal; and second amplifier circuitry configured to adjust a gain of the first amplified signal towards upstream and downstream neighbors of the linear wireless sensor in the linear wireless sensor network.
