Latest Patents
One of Andrew Wu's latest patents is titled "Adaptive noise cancelling for conferencing communication systems." This innovative communication system features a noise cancellation assembly that provides adaptive or dynamic noise cancellation. The assembly includes a localizer module that determines the location of the active talker during a communication session. It enhances the active talker's speech by forming a beam in the determined direction. The system intelligently assigns microphones to differentiate between the active signal source and noise sources, optimizing communication quality.
Another notable patent is the "Method and apparatus for detecting echo path changes in an acoustic echo canceller." This invention comprises a first adaptive filter that converges to an echo path and a non-adaptive filter that captures a direct echo path portion. The design allows for quick convergence at start-up and includes decision logic to distinguish between echo path changes and double-talk. This technology significantly improves the performance of acoustic echo cancellers.
