分子通信（MC）旨在为纳米技术开发一种有前途的生物启发通信范式，其中分子用于编码，传输和接收信息。MC中的主要挑战之一是由扩散信道的性质引起的码间干扰（ISI）。减少MC中ISI影响的最流行的解决方案是保持符号持续时间尽可能长，并减少在后续符号持续时间中可以接收的分子数量。另一方面，较长的符号持续时间会导致非常低的数据速率，即使距离非常短。此外，由于纳米级机器的尺寸，能源的生产成为一个重要问题。在本文中，ISI缓解技术的扩散为基础的分子通信信道，分子跃迁键控（MTSK）的建议，以提高数据速率，通过抑制ISI对通信质量的负面影响。MTSK采用多种分子类型，并且具有功率调节的MTSK的能量高效扩展版本（MTSK-PA）利用通道中的残留分子来减少ISI，否则ISI将有助于ISI。通过计算机仿真表明，MTSK和MTSK-PA优于文献中提出的标准调制技术。
Molecular communication (MC) aims to develop a promising bio-inspired communication paradigm for nanotechnology, in which molecules are used to encode, transmit, and receive information. One of the main challenges in MC is the intersymbol interference (ISI) caused by the nature of the diffusion channel. The most popular solution to reduce the effects of ISI in MC is to keep the symbol duration as long as possible and reduce the number of molecules that can be received in subsequent symbol durations. On the other hand, a long symbol duration leads to a very low data rate, even for very short distances. Furthermore, due to the size of the nano-scale machines, production of energy becomes an essential problem. In this paper, an ISI mitigation technique for diffusion-based molecular communication channels, titled Molecular Transition Shift Keying (MTSK) is proposed in order to increase the data rate via suppressing the negative impact of the ISI on communication quality. MTSK employs multiple molecule types and the energy efficient extended version of MTSK with power adjustment (MTSK-PA) makes use of the residual molecules in the channel to reduce the ISI that would otherwise contribute to the ISI. It is shown via computer simulations that both MTSK and MTSK-PA outperforms the standard modulation techniques proposed in the literature.
