Abstract

Molecular Communication via Diffusion (MCvD) aims to establish communication links at the nanoscale by utilizing chemical signals for information transmission. After encoding the bits in a physical property of a molecular wave, the transmitter releases the molecules into the fluid environment where they diffuse randomly according to the laws of Brownian motion. For consequent bit transmission scenarios, the random nature of the channel causes inter-symbol interference (ISI) for the system, which affects communication performance and poses limits on the range and the bit rate of the communication. Due to facing different amounts of ISI for different bit sequences, each sequence combination should be evaluated when deriving the theoretical bit error rate of an MCvD system. Emphasizing the fact that some bit sequences produce considerably more bit errors than others, this paper aims to reduce the number of evaluations required to derive theoretical approximate bit error rates while preserving sufficient precision.
降低分子通信复杂度的错误概率计算
分子扩散通信(MCvD)旨在利用化学信号进行信息传递,建立纳米级的通信链路。在以分子波的物理性质对比特进行编码后,发射器将分子释放到流体环境中,在那里它们根据布朗运动定律随机扩散。在后续的比特传输场景中,信道的随机性会对系统造成码间干扰(ISI),影响通信性能,并对通信的范围和比特率造成限制。由于不同比特序列的码间误码率不同,在推导MCvD系统的理论误码率时,需要对每种序列组合进行评估。强调一些比特序列比其他比特序列产生更多的误码率,本文旨在减少获得理论近似误码率所需的评估次数,同时保持足够的精度。
