Processing signals

摘要

Method, device and computer program product for processing signals. Signals are received at a plurality of sensors of the device. The initiation of a signal state in which signals of a particular type are received at the plurality of sensors is determined. Responsive to the determining of the initiation of the signal state, data indicating beamformer coefficients to be applied by a beamformer of the device is retrieved from data storage means, wherein the indicated beamformer coefficients are determined so as to be suitable for application to signals received at the sensors in the signal state. The beamformer applies the indicated beamformer coefficients to the signals received at the sensors in the signal state, thereby generating a beamformer output.

1. A method of processing signals at a device, the method comprising:
receiving signals at a plurality of sensors of the device; determining the initiation of an echo signal state in which signals including echo signals are received at the plurality of sensors; responsive to the determining the initiation of the echo signal state, retrieving, from a data store, data indicating beamformer coefficients to be applied by a beamformer of the device, the indicated beamformer coefficients being determined so as to be suitable for application to the signals received at the sensors in the echo signal state; and the beamformer applying the indicated beamformer coefficients to the signals received at the sensors in the echo signal state to generate a beamformer output.
