Title: Innovations of Alexander Volkov in Echo Cancellation Technology

Introduction

Alexander Volkov is an accomplished inventor based in Gilbert, AZ (US). He has made significant contributions to the field of digital signal processing, particularly in echo cancellation technology. His innovative approach has led to the development of a unique adaptive filter that enhances audio quality in various applications.

Latest Patents

Volkov holds a patent for a "Robust adaptive filter for echo cancellation." This adaptive filter is programmed with an algorithm based on a normalized Least Mean Squares (nLMS) algorithm that adapts each sample time. The algorithm is modified to be more efficient in a variety of digital signal processors (DSPs) by computing multiple errors, one per sample, before updating coefficients. The update equation utilizes these multiple errors to achieve adaptation at a performance level similar to known nLMS algorithms that adapt each sample time, but without the instability observed in low echo-to-near-end-noise ratio (ENR) input conditions. Additionally, varying the relaxation step size prevents divergence, and the DSP can utilize either one or more multiply-accumulate (MAC) units.
