In aeroacoustics, beamforming is a signal processing technology that is used to direct the reception or transmission (the signal energy) on a transducer array in a chosen angular direction. Beamforming concentrates the array to sounds coming from only one particular direction to listen to sounds in one direction and ignore sounds in other directions. Beamforming is one of several technologies, as well as smart antennas and MIMO, that is used boost the range and capacity of WiMAX by providing a better signal-to-noise(SNR) ratio.
