低复杂性优先：以持续时间为中心的ISI扩散分子通讯缓解
Low Complexity First: Duration-Centric ISI Mitigation in Molecular Communication via Diffusion
摘要：
在本文中，我们提出了一种新的符号间干扰（ISI）抑制方案的分子通信通过扩散（MCvD）系统的最佳检测间隔。其基本原理是利用丢弃的持续时间（即，该最佳间隔之外的符号持续时间）以减轻目标系统中的ISI。根据这一思想，我们制定了一个目标函数来量化丢弃时间对误比特率（BER）性能的影响。此外，还导出了适用于吸收接收机和无源接收机的最佳可重用间隔的封闭形式。最后，数值结果验证了我们的分析，并表明，对于所考虑的MCvD系统，可以实现显着的BER改善，通过使用派生的可重用的持续时间。
英文摘要：
In this paper, we propose a novel inter-symbol interference (ISI) mitigation scheme for molecular communication via diffusion (MCvD) systems with the optimal detection interval. Its rationale is to exploit the discarded duration (i.e., the symbol duration outside this optimal interval) to relieve ISI in the target system. Following this idea, we formulate an objective function to quantify the impact of the discarded time on bit error rate (BER) performance. Besides, an optimally reusable interval within the discarded duration is derived in closed form, which applies to both the absorbing and passive receivers. Finally, numerical results validate our analysis and show that for the considered MCvD system, significant BER improvements can be achieved by using the derived reusable duration.
