Latest Patents

Thomas Harley holds a patent for an acoustic echo canceller. This invention is a method and apparatus designed to cancel acoustic echoes, thereby improving the hands-free operation of audio and video conferencing equipment, as well as wireless and cellular telephones. The technology utilizes a constrained and orthogonalized, frequency domain, block, least mean square adaptive filter to generate an estimate of the acoustic echo signal. This estimate is then subtracted from a near-end microphone signal to produce an echo-reduced communication signal. The resulting signal can be transmitted or further processed, which may include non-linear processing using an adaptive speech filter. Additionally, the invention features a novel method for updating the coefficients of the adaptive filter.
