Beamforming
Beamforming is a signal processing technique used in wireless communication systems and microphone arrays to enhance the directionality of the signal. It involves combining the signals from multiple antennas or microphones in a way that amplifies the signal in the desired direction and suppresses the signal in other directions. Beamforming can be implemented using analog or digital signal processing techniques. In digital beamforming, the signals from the antennas or microphones are digitized and processed using algorithms such as the minimum variance distortionless response (MVDR) or the linearly constrained minimum variance (LCMV) to optimize the beam pattern. Beamforming has applications in various fields such as radar, sonar, wireless communication, and speech recognition.
