用于分子通讯的微流控QCSK发射器和接收器设计
Microfluidic QCSK Transmitter and Receiver Design for Molecular Communication
摘要：
具有分子通信（MC）功能的组件的设计可以带来机会，使从个人医疗保健到现代工业的一些新兴应用成为可能。在本文中，我们提出了设计的微流控发射器和接收器的四重浓度移键控（QCSK）调制和解调功能。为此，我们首先提出了一个“与”门的设计，然后将其应用到QCSK发射机和接收机的设计。QCSK发射器能够将两个输入信号调制为四个不同的浓度水平，QCSK接收器可以将接收到的信号解调为两个输出。更重要的是，我们还建立了一个数学框架，从理论上表征我们提出的微流体回路。在此基础上，我们首先推导出我们提出的“与”门设计的输出浓度分布，并提供了设计参数的选择，以确保所需的行为的展览洞察。我们进一步推导出QCSK发射机和接收机的输出浓度分布。在COMSOL Multiphysics中获得的仿真结果不仅显示了所有拟议的微流体回路的预期行为，而且还证明了所提出的数学框架的准确性。
英文摘要：
The design of components with molecular communication (MC) functionalities can bring an opportunity to enable some emerging applications in fields from personal healthcare to modern industry. In this paper, we propose the designs of the microfluidic transmitter and receiver with quadruple concentration shift keying (QCSK) modulation and demodulation functionalities. To do so, we first present an AND gate design, and then apply it to the QCSK transmitter and receiver design. The QCSK transmitter is capable of modulating two input signals to four different concentration levels, and the QCSK receiver can demodulate a received signal to two outputs. More importantly, we also establish a mathematical framework to theoretically characterize our proposed microfluidic circuits. Based on this, we first derive the output concentration distribution of our proposed AND gate design, and provide the insight into the selection of design parameters to ensure an exhibition of desired behaviour. We further derive the output concentration distributions of the QCSK transmitter and receiver. Simulation results obtained in COMSOL Multiphysics not only show the desired behaviour of all the proposed microfluidic circuits, but also demonstrate the accuracy of the proposed mathematical framework.
