Communication Method of Implant BAN for Medical Application

在本研究中，针对植入物BAN的实现，我们分别在400 MHz频段和UWB低频段为解剖人体模型开发了体内到体内的信道模型。利用这些信道模型，我们研究了适用于体内到体内传输的调制/解调方案，并开发了体内到体内的收发器进行实验验证。在综合考虑误码率等通信性能和SAR对人体安全评价的基础上，明确了两个频段的最大数据速率和允许发射功率。此外，我们还提出并证明了分集接收对提高误码率和SAR的有效性

In this study, aiming at implant BAN realization, we developed in-body to on-body channel models for an anatomical human body model in 400 MHz band and UWB low band, respectively. With these channel models we investigated the modulation/demodulation schemes suitable to the in-body to on-body transmission, and developed an in-body to on-body transceiver for experimental validation. Based on a comprehensive consideration on both the communication performance such as BER and the human safety evaluation by SAR, we clarified the maximum data rate and permissible transmit power in the two frequency bands. Moreover, we also proposed the adoption and demonstrated the usefulness of diversity reception on improving the BER and SAR at the same time
