Title: Innovations of Honghui Xu in Audio Technology

Introduction

Honghui Xu is a notable inventor based in Buffalo Grove, Illinois, recognized for his contributions to audio technology. With a total of six patents to his name, Xu has made significant advancements in wireless audio systems, particularly in the realm of in-ear monitoring.

Latest Patents

One of Xu's latest patents is the "Scalable Multiuser Audio System and Method." This invention describes systems, methods, apparatuses, and computer program products for wireless in-ear monitoring (IEM) of audio. The system includes transmitters that map orthogonal sub-carriers of a digital signal to narrowband receivers, forming receiver-allocated audio channels. It modulates the digital signal and transmits it as an ultra-high frequency (UHF) analog carrier wave comprising the orthogonal sub-carriers to nearby receivers. The narrowband receiver is designed to demodulate and sample the allocated sub-carriers. The sub-carriers can be positioned orthogonally in adjacent sub-bands of the frequency domain, with beacon symbols and pilot signals iteratively provided in the same portion of the frequency domain for each channel. The receiver employs both non-data-aided and data-aided approaches for synchronizing the time domain and frequency domain waveforms of the received signal to the transmitted signal before sampling the allocated sub-carriers.

Career Highlights

Throughout his career, Honghui Xu has worked with prominent companies in the audio industry, including Shure Acquisition Holdings, Inc. and Techwell, Inc. His experience in these organizations has contributed to his expertise in developing innovative audio solutions.
