Title: Thi Hong Thu Nguyen: Innovator in Acoustic Echo Cancellation
Introduction
Thi Hong Thu Nguyen is a notable inventor based in Ichinomiya, Japan. He has made significant contributions to the field of acoustic echo cancellation, holding 2 patents that showcase his innovative approach to solving complex audio challenges. His work is particularly relevant in environments where clear communication is essential.
Latest Patents
Nguyen's latest patents include an "Echo canceller with variable step-size control" and "Systems and methods of echo reduction." The first patent describes an acoustic echo canceller (AEC) that utilizes a simulated echo from an adaptive filter to effectively cancel actual echoes from real environments. This technology optimizes echo cancellation by adjusting the coefficients of the filter in a step-wise manner, ensuring that the filter converges on a configuration that yields the best results. The AEC is designed to adapt to disruptive events, such as double talk or changes in the environment, by modifying the step-size of the adaptive algorithm.
The second patent outlines a method for echo reduction that involves producing acoustic waves through a loudspeaker based on a far-microphone signal. It details the process of receiving echoes at a local microphone and generating a local-microphone signal. The method includes producing an estimated-echo signal and summing it with the local-microphone signal to create a resultant signal with reduced echo. This innovative approach also involves controlling the current step-size parameter based on a calculated convergence value.
