近年来，分子通信作为细胞间或分子机器人间的微尺度通信被广泛研究。在以往的工作中，对无界环境下的MC信道进行了分析。然而，许多实验实现的MC通道被壁包围，因此在分析MC通道动力学时应明确考虑边界条件。本文提出了一个基于带边界的扩散方程的一维MC信道频率响应分析框架。特别地，我们将MC信道分解为扩散系统和边界系统，并基于传递函数给出了MC信道的截止频率与通信距离的关系。然后，我们分析了特定MC信道的频率响应，并揭示了边界可以限制MC信道的通信带宽。
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.
