Latest Patents

Yi-Rou Chen holds a patent for "Recursive training of adaptive filters for active noise control (ANC) systems." This patent provides methods, devices, and systems for active noise control. The implementation details techniques for recursively training an infinite impulse response (IIR) filter to convert a reference audio signal into an anti-noise signal. The ANC system records external noise through a feedforward microphone and captures residual noise via a feedback microphone. It estimates an IIR filter that converts the reference audio signal to the error signal based on a secondary path. The system updates the IIR filter coefficients recursively, utilizing coefficients from previous frames of the reference audio signal and the error signal. Yi-Rou Chen has 1 patent to his name.
