Latest Patents

One of Sean's latest patents is a low-complexity comfort noise generator. This invention is designed for use in communication systems and includes a finite impulse response (FIR) filter, a random number generator, and a coefficient updater. The coefficient updater determines an updated set of filter coefficients based on the signal frame of the input signal. The FIR filter shapes a white noise signal supplied by the random number generator to provide a simulated background noise signal, or comfort noise signal. This comfort noise signal is selectively output from an echo suppression system to overwrite or suppress reflected residual echoes.

Another significant patent is for automatic gain control for an adaptive finite impulse response and the method associated with it. This invention provides methods and apparatus for an echo cancellation system, which comprises an automatic gain control (AGC), a first scalar, a second scalar, a signal summing stage, and an adaptive filter. The AGC responds to signals in both a reference path and a near-end path, ensuring effective echo cancellation.
