分子通讯中干扰分子降解的有效酶配置
Effective Enzyme Deployment for Degradation of Interference Molecules in Molecular Communication
摘要：
在分子通信中，分子信号的重尾特性导致符号间干扰（ISI）。因此，难以减小符号周期并实现高数据率。作为ISI缓解的可能解决方案，提出使用酶，因为它们能够降解ISI分子而不破坏分子通讯。虽然大多数先前的工作已经假设在通道周围部署了无限数量的酶，但从资源的角度来看，在特定位置和结构处部署有限数量的酶更有效。本文考虑进行这样的部署在两个结构-周围的接收器（Rx）和/或发射器（Tx）的网站。对于这两种部署场景，将具有不同系统环境参数（Tx到Rx距离、酶区域的大小和符号周期）的信道彼此进行比较，以分析当有限量的酶可用时用于ISI缓解的优化系统环境。
英文摘要：
In molecular communication, the heavy tail nature of molecular signals causes inter-symbol interference (ISI). Because of this, it is difficult to decrease symbol periods and achieve high data rate. As a probable solution for ISI mitigation, enzymes were proposed to be used since they are capable of degrading ISI molecules without deteriorating the molecular communication. While most prior work has assumed an infinite amount of enzymes deployed around the channel, from a resource perspective, it is more efficient to deploy a limited amount of enzymes at particular locations and structures. This paper considers carrying out such deployment at two structures--around the receiver (Rx) and/or the transmitter (Tx) site. For both of the deployment scenarios, channels with different system environment parameters, Tx-to-Rx distance, size of enzyme area, and symbol period, are compared with each other for analyzing an optimized system environment for ISI mitigation when a limited amount of enzymes are available.
