摘　　要：无线体域网(WBAN)是穿戴式监测技术中关键的一环,当前有着诸多的通信技术可供选择,像蓝牙、ZigBee、超宽带(UWB)、无线人体通信(WHBC)等。其中WHBC是最近几年才兴起的技术,有着强劲的增长势头,在组建WBAN这一方面有着天然的优势,值得我们去深入研究。本篇论文先简单介绍了WHBC的技术背景,然后讲述了WHBC的理论模型和基于WHBC的数字传输机,最后分析了WHBC中的各种干扰并阐述了能有效应对干扰的自适应跳频(AFH)技术。The Wireless Body Area Network （WBAN） is a key part of the wearable monitoring technologies, which has many communication technologies to choose from, like Bluetooth, ZigBee, Ultra Wideband, and Wireless Hu- man Body Communication （WHBC）. As for the WHBC developed in recent years, it is worthy to be further studied. The WHHBC has a strong momentum of growth and a natural advantage in the formation of WBAN. In this paper, we first briefly describe the technical background of WHBC, then introduce theoretical model of human-channel commu- nication and digital transmission machine based on human channel. And finally we analyze various of the interference of the WHBC and show the AFH （Adaptive Frequency Hopping） technology which can effectively deal with the in- terference.
