An effective beamformer for interference suppression without knowing the direction

<span>This paper proposes an effective beamformer for uniform linear arrays of half-wave dipole antennas based on binary bat algorithm (BBA) by controlling complex weights (both amplitudes and phases) excited at elements in array. The proposed can impose adaptive nulls interferences without knowing directions the sidelobe region minimizing total output power array, whereas main lobe levels are maintained. To demonstrate this capability, proposal will be evaluated several scenarios, compared to a particle swarm optimization (BPSO).</span>
