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.
