Latest Patents

Wouter Dehandschutter holds a patent for a "Noise-level adaptive residual echo suppressor." This advanced echo control system features an adaptive controlled echo canceling filter arrangement. The system includes a background filter that updates the filter coefficients of an echo shaping filter using a normalized least mean square (NLMS) algorithm. An adaptive control module determines a weighted reference signal for the background filter, where the weight is proportional to a far signal reference and an estimate of the norm of an echo canceller error vector. Additionally, it is inversely proportional to an estimate of a residue of the echo canceller. A non-linear normalized convergence term is utilized in the NLMS algorithm, making this invention a significant advancement in echo suppression technology.
