Beamforming is a signal processing method intended to perform a spatial filtering in which an array of receiving antennas is employed to achieve full signal reception in a specified path by estimating the signal coming from a desired direction (in the presence of noise) while signals of the similar frequency from other directions are rejected. This is achieved by varying the weights of each of the receiving sensors (antennas) used in the array. It basically uses an idea that, though the signals originating from different transmitters inhabit the identical frequency channel, they still arrive from various directions.
