AB  - We propose a cooperative beamforming technique with directional beams and analyze its beampattern characteristics and sidelobe suppression performance.
Compared to the conventional case where electromagnetic waves are radiated isotropically, the proposed system improves the average power in the target node direction, but the beamwidth and sidelobes also increase. Fortunately, we also show that beamwidth control enables effective sidelobe suppression.
