| Zusammenfassung: | The invention discloses a communication network time synchronization device comprising a transmitting channel and a receiving channel. The communication network time synchronization device is characterized in that the transmitting channel processes service data to output a dynamic group delay transmitting signal and comprises a multi-burst time hopping transmitting module and a controllable group delay transmission filter when a pulse transmitting mode is time hopping; and the receiving channel processes a matched, extracted and received complex baseband signal, outputs accurate measurement pulses Tmeasure used for measuring an inquiry receiving moment T1 and a reply receiving moment T3, and comprises a single-burst timing synchronization module, an up-sampling module and a multi-burst joint synchronization module. The communication network time synchronization device disclosed by the invention realizes the purpose of communication network time synchronization through calculation with low complexity and high |
