Latest Patents

Shih Hau Fang holds a patent for an "Acoustic echo cancellation method and system using the same." This patent outlines a method that involves building a prior-knowledge matrix with multiple space vectors. The process begins with generating an initial filter vector and an initial weighting vector. The weighting vector is then updated based on the difference between the echo signal and the estimated signal through an iterative algorithm. Subsequently, the filter vector's coefficient is adjusted according to the updated weighting vector. The method culminates in generating an estimated signal from the updated filter vector and the original signal, effectively cancelling the next echo signal using the near-end estimated signal. He has 1 patent to his name.
