摘要:

分子通信(MC)利用扩散的力将分子从发射机传输到接收机。文献中已广泛研究了基于分子浓度、类型和释放时间的多种调制技术。在本文中,我们提出了一种新颖的调制技术,将信息编码到多个分子的相对浓度中,称为多比率移位键控(MRSK),专为无漂移的基于扩散的MC而设计。我们表明,利用一组分子中所有可能的比率有助于减轻符号间干扰(ISI)的影响,并提供灵活的通信信道。为了评估MRSK的性能,我们开发了一个数学框架,用于研究随机变量比率的统计特性,重点关注非中心高斯分布。然后,我们在各种信道条件下通过解析方法和基于粒子的仿真评估MRSK性能,识别系统模型中潜在的误差来源。此外,我们基于误码率(BER)对文献中常用的调制方案进行了比较分析。结果表明,在BER方面,MRSK显著优于本研究中考虑的所有传统调制方案。MRSK为MC范式的未来提供了一种有前景、灵活且更可靠的通信方法。

英文摘要:

Molecular Communication (MC) leverages the power of diffusion to transmit molecules from a transmitter to a receiver. A wide variety of modulation techniques based on molecule concentration, type, and release time have been extensively studied in the literature. In this paper, we propose a novel modulation technique that encodes the information into the relative concentrations of multiple molecules called Multi Ratio Shift Keying (MRSK) designed for diffusion-based MC without drift. We show that leveraging all possible ratios in a set of molecules can help mitigate the effects of intersymbol interference (ISI) and provide a flexible communication channel. To evaluate the performance of the MRSK, we develop a mathematical framework for studying the statistics of the ratio of random variables, focusing on noncentral Gaussian distributions. We then assess MRSK performance both analytically and through particle-based simulations under various channel conditions, identifying potential sources of error in our system model. Additionally, we conduct a comparative analysis of commonly used modulation schemes in the literature based on bit error rate (BER). The results show that MRSK significantly outperforms all traditional modulation schemes considered in this study in terms of BER. MRSK offers a promising, flexible, and more reliable communication method for the future of the MC paradigm.
