无线体域网络（WBAN）是一项将医疗保健和消费电子应用于人体周围的新兴技术。在IEEE 802.15.6 WBAN标准化任务组中讨论了三种PHY方案：超宽带（UWB） PHY、窄带（NB） PHY和体信道通信（BCC） PHY。BCC是利用人体作为基于近场耦合机制的通信信道，在150MHz以下的低频段内没有身体阴影效应，路径损耗小，在能量效率上优于UWB和NB[2-4]。然而，以往的主体信道收发器（bct）没有针对WBAN进行优化，因为仅使用现象学电路模型进行主体信道分析[5]，无法同时满足能源效率、QoS可扩展性、干扰缓解和共存等要求。
Wireless Body Area Network (WBAN) is an emerging technology that combines health care and consumer electronic applications around the human body. There are 3 PHY schemes discussed in the IEEE 802.15.6 Task Group for WBAN standardization [1]: ultra-wide-band (UWB) PHY, narrow-band (NB) PHY, and body channel communication (BCC) PHY. The BCC, which uses the human body as a communication channel based on the near-field coupling mechanism, has advantages over UWB and NB in energy efficiency because it provides low path-loss without the body shadowing effect in low-frequency bands below 150MHz [2–4]. However, the previous body channel transceivers (BCTs) were not optimized for WBAN because only phenomenological circuit models were used for the body channel analysis [5] and were unable to satisfy requirements such as energy efficiency, scalability of QoS, interference mitigation, and coexistence at once.
