Abstract
A system and method for generating a self-steering beamformer is provided. Embodiments may include receiving, at one or more microphones, a first audio signal and adapting one or more blocking filters based upon, at least in part, the first audio signal. Embodiments may also include generating, using the one or more blocking filters, one or more noise reference signals. Embodiments may further include providing the one or more noise reference signals to an adaptive interference canceller to reduce a beamformer output power level.
Claims20
A computer-implemented method comprising:
- receiving, at one or more microphones, a first audio signal;
- adapting one or more blocking filters based upon, at least in part, the first audio signal;
- generating, using the one or more blocking filters, one or more noise reference signals;
- and
- providing the one or more noise reference signals to an adaptive interference canceller to reduce a beamformer output power level.
2 more elements
A system comprising:
- one or more microphones;
- and
- one or more processors configured to receive a first audio signal, the one or more processors configured to adapt one or more blocking filters based upon, at least in part, the first audio signal, the one or more processors further configured to generate, using the one or more blocking filters, one or more noise reference signals, the one or more processors further configured to provide the one or more noise reference signals to an adaptive interference canceller to reduce a beamformer output power level.
