中文摘要：
在无线网络，合作通讯的多数在孤立的节点之中依靠高精确性的预定同步。然而，大多数介绍物理层的分布式的同步算法到目前为止不能为真实应用程序满足要求。认识到分布式的钟的频率和阶段同步，即，完整的同步，由它可以帮助的比例的正不可分的控制器的特性启发了一个不稳定的系统是一个不不变的错误一个，分布式的分离锁阶段的循环(PLL ) 的新环结构被设计。由使用代数学的图理论，而且，这个计划的集中被分析为指导了，未受指导的网络，和完整的同步被证明被到达。模拟结果被给支持建议算法和分析。
英文摘要：
In wireless networks, the majority of cooperative communications rely on the high-accuracy timing synchronization among isolated nodes. However, most presented physical-layer distributed synchronization algorithms so far cannot satisfy the requirement for real applications. To realize frequency and phase synchronization of distributed clocks, i.e., full synchronization, inspired by the character of the proportional plus integral controller that it may help an unstable system be a no steady-state error one, a new loop structure of distributed discrete phase-locked loop （PLL） is designed. Furthermore, by using algebraic graph theory, the convergence of this scheme is analyzed for both directed and undirected networks, and full synchronization is proved to be reached. Simulation results are given to corroborate the proposed algorithm and analysis.
