Precision Time Synchronization Consistency Algorithm for Multi-Node Dynamic Time-Frequency Synchronization Networks

With the rapid development and application of communication networking technology, the traditional time synchronization method has limited accuracy and cannot meet the demand for time synchronization accuracy and stability of multi-node and dynamic characteristics of today's wireless cluster time-frequency synchronization networks. In this paper, we propose a precise and consistent synchronization algorithm for multi-node dynamic time-frequency synchronization networks, build a multi-node dynamic network synchronization system based on multi-intelligence consistency theory, propose a consistent synchronization algorithm for multi-node dynamic time-frequency synchronization networks, and evaluate the measurement results of the ultra-wideband time-frequency synchronization system and simulate and analyze the synchronization effect under different topologies. The results show that the measured data are relative to the clock frequency. The results show that the relative clock frequency and clock frequency stability of the measured data can achieve better than nanosecond level, in which the ADEV is finally stabilized at 1.6e-10; and the better the topology network connectivity, the faster the synchronization convergence speed and the higher the steady-state accuracy.
