Capacity of Discrete Molecular Diffusion Channels

Arash Einolghozati, Mohsen Sardari, Ahmad Beirami, Faramarz Fekri

摘要:

在基于扩散的分子通信中,可以通过介质中分子浓度的变化来传递消息。在本文中,我们打算分析的信息从一个节点到另一个节点的扩散通道中的可实现的容量。我们观察到,由于介质中的分子扩散,通道具有记忆性。然后,我们通过两步马尔可夫链的信道的记忆模型,并获得描述的扩散信道的容量的方程。通过执行数值分析,我们获得了对于不同电平的发射机功率的最大可实现速率,即,分子生产率。

英文摘要:

In diffusion-based molecular communications, messages can be conveyed via the variation in the concentration of molecules in the medium. In this paper, we intend to analyze the achievable capacity in transmission of information from one node to another in a diffusion channel. We observe that because of the molecular diffusion in the medium, the channel possesses memory. We then model the memory of the channel by a two-step Markov chain and obtain the equations describing the capacity of the diffusion channel. By performing a numerical analysis, we obtain the maximum achievable rate for different levels of the transmitter power, i.e., the molecule production rate.
