摘要：
在新兴的分子通信（MC）领域，需要测试平台来验证理论概念，激励应用程序，并指导进一步的建模工作。为此，本文提出了一个灵活的和可扩展的容器内测试平台，用于基于流动的宏观MC，抽象建模，例如，化学反应器或血管的一部分。信号是基于注入非反应性超顺磁性氧化铁纳米粒子（SPION）分散在水悬浮液到管与背景流。商用磁敏仪用于非侵入式下游信号接收。为了阐明测试平台的操作，我们确定的物理机制管理的传输，传播和接收的信息携带SPION。此外，为了便于系统设计，我们提出了一个封闭形式的参数表达式的端到端的信道脉冲响应（CIR）。建议的CIR模型示出一致地捕获实验观察到的距离相关的脉冲响应的峰值高度和峰值衰减的传输距离从5cm到40cm。此外，为了验证我们的测试平台，可靠的通信模型无关和基于模型的检测方法的实验数据的基础上证明。
英文摘要：
In the emerging field of molecular communication (MC), testbeds are needed to validate theoretical concepts, motivate applications, and guide further modeling efforts. To this end, this paper presents a flexible and extendable in-vessel testbed for flow-based macroscopic MC, abstractly modeling, e.g., a part of a chemical reactor or a blood vessel. Signaling is based on injecting non-reactive superparamagnetic iron oxide nanoparticles (SPIONs) dispersed in an aqueous suspension into a tube with background flow. A commercial magnetic susceptometer is used for non-intrusive downstream signal reception. To shed light on the operation of the testbed, we identify the physical mechanisms governing the transmission, propagation, and reception of the information-carrying SPIONs. Moreover, to facilitate system design, we propose a closed-form parametric expression for the end-to-end channel impulse response (CIR). The proposed CIR model is shown to consistently capture the experimentally observed distance-dependent impulse response peak heights and peak decays for transmission distances from 5cm to 40cm. Moreover, to validate our testbed, reliable communication is demonstrated based on experimental data for model-agnostic and model-based detection methods.
