摘要

认知无线网络(CRN)具有分布式特性，协作行为是其关键。时间同步是合作的基础。开发了许多协议。然而，它们要么相当复杂，要么依赖GPS等基础设施。本文提出了一种物理层方法。该方法不需要复杂的协议，且对其他系统不可靠，具有较高的效率。提出了同步方法，并搭建了相应的平台。分析了同步误差对系统性能的影响，并给出了解决方法。

A physical layer approach for time synchronization in cognitive communication systems

Cooperative behavior is vital to Cognitive Radio Networks (CRN), which has the distributed nature. Time synchronization is the basic to cooperation. Many protocols are developed. However, they are either rather complicated or relying on infrastructure such as GPS. In this paper, a physical layer approach is proposed. Without complex protocols and not reliable to other systems, this approach has a better efficiency. The synchronization method is proposed and the corresponding platform is demonstrated. The analysis on how the error of synchronization deteriorates the performance is given and the solutions are shown thereafter.
