A software radio bidirectional time synchronization method based on active timing control
By employing a software-defined radio bidirectional time synchronization method with active timing control, the transmission timing is dynamically restored and the reception process is seamlessly connected. This solves the synchronization accuracy and stability problems caused by the limited buffer of the USRP device, and achieves high-precision, long-term stable time synchronization.

Abstract
The application provides a software radio bidirectional time synchronization method based on active timing control, which comprises the following steps: performing a signal transmission process at a communication node to transmit a synchronization signal to a peer node, wherein the signal transmission process performs a dynamic timing recovery process; performing a signal receiving process at the communication node to receive and process the synchronization signal of the peer node, wherein the signal receiving process performs a seamless timing connection process; and the dynamic timing recovery process and the seamless timing connection process work cooperatively to realize bidirectional time synchronization. Without relying on special hardware, the application can realize long-term stable operation of radio high-precision synchronization.
