The advancement in nanotechnology has promoted the development of molecular communication. Nano-devices can communicate with each other by molecular communication at the nano- or micro-scale. The distance between the nanomachines is an important parameter in the molecular communication system. It is needed in the clock synchronization protocol, the transmission rate optimization, etc. In this paper, we propose a high-accuracy protocol for estimating distance based on maximum likelihood estimation (MLE). The receiver nanomachine estimates the distance by sampling the concentration from multiple symbols. The inter-symbol interference (ISI) and additive noise are considered. The Newton–Raphson method is used to calculate the estimated distance. The performance of the proposed protocol is evaluated by simulations in MATLAB. The results show that the proposed scheme achieves good performance in the ISI scenario compared with the existing schemes in terms of accuracy, but in the sacrifice of more computational resources.

通过扩散对分子通信系统进行高精度距离估计

纳米技术的进步促进了分子通讯的发展。纳米设备可以通过纳米或微米级别的分子通信相互通信。纳米机器之间的距离是分子通讯系统中的重要参数。在时钟同步协议,传输速率优化等方面都需要它。在本文中,我们提出了一种基于最大似然估计(MLE)的高精度距离估计协议。接收器纳米机通过从多个符号中采样浓度来估计距离。考虑了符号间干扰(ISI)和加性噪声。牛顿-拉夫森法用于计算估计距离。通过在MATLAB中进行仿真,可以评估所提出协议的性能。
