论文摘要
最近,已经研究了分子通信(MC)作为细胞或分子机器人之间的微尺度通信。在以前的工作中,分析了无限环境中的MC频道。但是,许多实验实现的MC通道都被墙壁包围,因此应明确考虑边界条件以分析MC通道的动力学。在本文中,我们提出了一个框架,以分析基于边界扩散方程的一维MC通道的频率响应。特别是,我们将MC通道分解为扩散系统和边界系统,并根据传输函数显示MC通道的截止频率与通信距离之间的关系。然后,我们分析特定MC通道的频率响应,并揭示边界可以限制MC通道的通信带宽。
Recently, molecular communication (MC) has been studied as a micro-scale communication between cells or molecular robots. In previous works, the MC channels in unbounded environment was analyzed. However, many of the experimentally implemented MC channels are surrounded by walls, thus the boundary condition should be explicitly considered to analyze the dynamics of MC channels. In this paper, we propose a framework to analyze the frequency response of one-dimensional MC channels based on a diffusion equation with a boundary. In particular, we decompose the MC channel into the diffusion system and the boundary system, and show the relation between the cut-off frequency of the MC channel and the communication distance based on the transfer function. We then analyze the frequency response of a specific MC channel and reveal that the boundary can restrict the communication bandwidth of the MC channel.
