Title: Inventor Yaqin Yong: Pioneering Adaptive Echo Cancellation Technology
Introduction: Yaqin Yong, an innovative inventor based in Shanghai, China, has made significant strides in the field of signal processing. With two patents to his name, he has contributed valuable methods and apparatuses aimed at reducing echo, particularly in systems plagued by distortion.
Latest Patents: Yaqin Yong's latest patents include the "Method and Apparatus for Reducing Distortion Echo" and the "Method and Apparatus for Reducing Echo." The first patent introduces a systematic approach to enhance echo cancellation by applying K-path amplification and pre-distortion processes to downlink reference signals. The use of self-adaptive filters allows for precise filtering of signals, ultimately producing error signals that contribute to a refined final output for echo cancellation. The method notably ensures substantial echo loss, especially beneficial when speakers exhibit significant distortion.
The second patent outlines a similar yet robust methodology for echo reduction. It employs a two-stage adaptive filtering process, where the first stage filters a reference signal, followed by K-path processing, and culminates in a minimum value fusion process. This ensures steady high echo loss even in challenging conditions, underscoring Yong’s innovative approach to enhancing auditory experiences.
