Title: Innovations of Hongyang Deng

Introduction

Hongyang Deng is a notable inventor based in Austin, TX (US). He has made significant contributions to the field of communication systems, holding a total of 5 patents. His work focuses on enhancing the performance of echo cancellers and adaptive filters, which are crucial in modern communication technologies.

Latest Patents

One of his latest patents is titled "Techniques for implementing adaptation control of an echo canceller to facilitate detection of in-band signals." This technique involves detecting in-band signaling tones in a communication system by adapting an echo canceller's filter in response to far-end harmonic signals. The adaptive filter provides an echo estimation signal, which is then subtracted from a near-end signal containing in-band signaling tones to yield an error signal. A tone detector is subsequently used to identify the in-band signaling tones within this error signal.

Another significant patent by Hongyang Deng is "Techniques for updating filter coefficients of an adaptive filter." This technique describes a method for updating filter coefficients of an adaptive filter, where the coefficients are organized into filter blocks. During each update period, the coefficients for a subset of these filter blocks are updated based on the network echo path impulse response, optimizing the filter's performance.
