A Meter-Range UWB Transceiver Chipset for Aroundthe-Head Audio Streaming

📋 论文概要

该论文提出了一种用于头部周围音频流的米范围UWB收发器芯片组，解决了无线音频耳机和助听设备在耳间、耳与播放器之间等多链路通信中的低功耗和高可靠性挑战。

💡 主要创新点

• 针对头部周围无线环境，设计了支持多链路（耳-耳、耳-口袋等）的UWB收发器架构。
• 实现了米级距离下的低功耗音频流传输，适合电池供电的耳戴式设备。
• 采用芯片组方案，集成了UWB射频前端和基带处理，优化了系统能效和链路稳定性。

This is especially true in the case of audio streaming around the head e.g. for wireless audio headsets or hearing-aid devices. The behind-the-ear device typically serves multiple radio links e.g. ear-to-ear, ear-to-pocket (a phone or MP3 player) or even a link between the ear and a remote base station such as a TV. Good audio quality is a prerequisite and mW-range power consumption is compulsory in view of battery size. However, the GHz communication channel typically shows a significant attenuation; for an ear-to-ear link, the attenuation due to the narrowband fade dominates and is in the order of 55 to 65dB [1]. The typically small antennas, close to the human body, add another 10 to15dB of losses. For
