Abstract

Sophisticated medical implants that allow vital information delivery to/from the human body are opening the door to novel approaches in diagnosis and/or therapy of various health related issues. Ultra-Wide Band (UWB) technology is gaining the attention of researchers as a possible candidate for implant communication due to its high data rate and low power consumption capabilities. Characterization of a propagation channel often involves a measurement campaign (either virtual or physical) and selecting a set of candidate test points (i.e. sample measurement points) through which numerical values of the desired signal at the receiver are collected. Statistical analysis of those data will lead to a channel model representing the communication link. Focusing on UWB implant channel characterization, this paper aims to highlight the potential impact of the measurement points location distribution on the extracted parameters of the channel model. This is achieved through emulating a custom-design multi-layer liquid phantom measurement system and performing a sequence of matching simulations with different sample point distributions. The results are meant to serve as a guideline for future UWB implant measurement campaigns.
测点分布对UWB植入通道模型参数的影响
复杂的医疗植入物允许重要信息从人体传递,为各种健康相关问题的诊断和/或治疗开辟了新的途径。超宽带(UWB)技术因其高数据速率和低功耗能力而成为植入通信的潜在候选技术,正受到研究人员的关注。传播信道的表征通常涉及测量活动(虚拟或物理)和选择一组候选测试点(即样本测量点),通过这些测试点收集接收器处所需信号的数值。对这些数据进行统计分析将得出一个表示通信链路的信道模型。本文以UWB植入物通道表征为重点,重点研究测点位置分布对通道模型提取参数的潜在影响。这是通过模拟一个定制设计的多层液体模体测量系统,并执行一系列匹配模拟与不同的样本点分布来实现的。结果旨在为未来的超宽带植入物测量活动提供指导。
