Cancellation of interfering audio on a mobile device

摘要

Generally, this disclosure provides devices, systems and methods for cancelling an interfering audio signal. The system may include a mobile device including a microphone configured to capture an acoustic audio signal, the acoustic audio signal a combination of the interfering audio signal and a desired audio signal, the desired audio signal generated by a user of the mobile device. The system may also include a wireless communication module incorporated in the mobile device, to receive a reference signal through a side-channel, the reference signal associated with the interfering audio signal. The system may further include an acoustic echo cancellation module incorporated in the mobile device, the acoustic echo cancellation module to cancel the interfering audio signal from the captured acoustic audio signal, the cancellation based on the reference signal.

主权项

1. A system for cancelling an interfering audio signal, said system comprising:
a mobile device comprising a microphone to capture an acoustic audio signal, said acoustic audio signal comprising a combination of a delayed version of said interfering audio signal and a desired audio signal, said desired audio signal generated by a user of said mobile device; wireless communication circuitry incorporated in said mobile device to receive a wireless communication signal, including a reference signal generated based on said interfering audio signal, through a side-channel comprising a wireless communication link between a source of said interfering signal and said mobile device; and acoustic echo cancellation circuitry incorporated in said mobile device, said acoustic echo cancellation circuitry to cancel said delayed version of said interfering audio signal from said captured acoustic audio signal, said cancellation based on said reference signal.
