本文探讨了分布式无线系统的分布式同步的历史、最新进展和挑战。它侧重于基于在物理层的信号交换和相应的基带处理的同步方案，其中可以使用来自信号处理的已知工具来执行分析和设计。重点讨论了分布式同步和分布式估计/检测问题之间的协同作用。最后，我们谈到了非周期(混沌)信号的同步。总体而言，我们希望传达这一主题的相关性，并就尚未解决的问题和现有的分析工具提供见解，以启发信号处理界的进一步研究。
This article has explored history, recent advances, and challenges in distributed synchronization for distributed wireless systems. It is focused on synchronization schemes based on exchange of signals at the physical layer and corresponding baseband processing, wherein analysis and design can be performed using known tools from signal processing. Emphasis has also been given on the synergy between distributed synchronization and distributed estimation/detection problems. Finally, we have touched upon synchronization of nonperiodic (chaotic) signals. Overall, we hope to have conveyed the relevance of the subject and to have provided insight on the open issues and available analytical tools that could inspire further research within the signal processing community.
