生物信号监测的下一个发展步骤将通过无线通信来实现。除了监测、监视和家庭自动化等军事和民用应用之外，低功耗且经济高效的无线收发器目前还用于植入式医疗设备 (IMD)。本文的主要目标是对工作在 3-5 GHz 超宽带频率下的植入式无线收发器进行彻底而现实的链路预算分析，链路距离为 2 m（包括 10 mm 的脑组织层和 1.99 m 的空气介质），采用开关键控 (OOK) 调制的数据速率为 100 Mbps，最小接收器灵敏度为 −58.01 dBm。所提出的功率预算分析特别适合分布式脑植入应用，因为它对包括组织层在内的路径损耗进行建模，而不会影响联邦通信委员会 (FCC) 对 UWB 通信实施的频谱规定。
The next evolutionary step in biological signal monitoring will be enabled by wireless communication. Low power and cost-efficient wireless transceivers are currently being employed for implantable medical devices (IMDs), in addition to military and civilian applications such as monitoring, surveillance, and home automation. The major goal of this paper is to do a thorough and realistic link budget analysis for an implantable wireless transceiver operating in the 3–5 GHz ultrawideband frequency with a link distance of 2 m (which includes 10 mm of brain tissue layer and 1.99 m of air medium), data rate of 100 Mbps with On-Off keying (OOK) modulation, and a minimum receiver sensitivity of −58.01 dBm. The proposed power budget analysis is particularly well suited for distributed brain implant applications as it models the path loss including the tissue layer without compromising the spectrum regulation imposed by the Federal Communications Commission (FCC) for UWB communication.
