Abstract

Recently, smart phones or head-mounted displays enables high definition (HD) video streaming and image data to be shared with friends while wearable smart sensors continuously monitor and send user's physiological information to a smart watch. Body channel communication (BCC), which uses the human body as the communication channel [1], has demonstrated better human-friendly interface and energy-efficient performance compared with air channel communication. However, most of the previous BCC research used only the frequency band below 100MHz and were only focused on either low data rate (<;10Mb/s) healthcare applications [2-5] or high data rate (60Mb/s) multimedia data transfer [6]. Its available channel bandwidth was limited <; 100MHz and the interference from FM radio due to body antenna effect had a significant effect on its performance. Moreover, [6] did not support full duplex communication so that the user interaction with wearable devices was not possible in live video streaming or real-time VR game applications.

21.1机身信道通信采用79pJ/b 80Mb/s全双工收发器和42.5μW 100kb/s超再生收发器

最近，智能手机或头戴式显示器可以与朋友分享高清视频流和图像数据，而可穿戴智能传感器可以持续监测用户的生理信息并将其发送给智能手表。身体通道通信(Body channel communication, BCC)以人体为通信通道[1]，与空气通道通信相比，具有更好的人性化界面和节能性能。然而，以往的BCC研究大多只使用100MHz以下的频段，并且只关注低数据速率(< 10Mb/s)的医疗保健应用[2-5]或高数据速率(60Mb/s)的多媒体数据传输[6]。其可用信道带宽有限<;100MHz和调频收音机由于机身天线效应的干扰对其性能有显著影响。此外，[6]不支持全双工通信，因此在实时视频流或实时VR游戏应用中无法实现用户与可穿戴设备的交互。
