Abstract

The process of combining signals acquired by a microphone array in order to ‘focus’ on a signal in a specific direction is known as beamforming or spatial filtering. This chapter considers signal-independent (fixed) beamformers, controlled by weights only dependent on the direction of arrival of the source to be extracted, and which do not otherwise depend on the desired signal. Because the weights of these beamformers are given by simple expressions, they present the advantages of being straightforward to implement and of having low computational complexity.
