近来，智能电话或头戴式显示器使得能够与朋友共享高清晰度（HD）视频流和图像数据，同时可穿戴智能传感器连续地监测用户的生理信息并将其发送到智能手表。身体通道通信（BCC）使用人体作为通信通道[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，大多数先前的BCC研究仅使用低于100 MHz的频带，并且仅关注低数据速率（<; 10 Mb/s）医疗保健应用[2-5]或高数据速率（60 Mb/s）多媒体数据传输[6]。它的可用信道带宽有限，小于100 MHz，由于人体天线效应，来自FM收音机的干扰对其性能有很大影响。此外，[6]不支持全双工通信，因此用户无法在实时视频流或实时VR游戏应用中与可穿戴设备进行交互。
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.
