Title:
SYNCHRONIZATION APPARATUS, SYNCHRONIZATION SYSTEM, WIRELESS COMMUNICATION APPARATUS AND SYNCHRONIZATION METHOD
Document Type and Number:
WIPO Patent Application WO/2014/083725
Kind Code:
A1
Abstract:
The objective of the invention is to provide a synchronization apparatus, a synchronization system, a wireless communication apparatus and a synchronization method that can suppress the affection of fluctuations occurring in a case of receiving synchronization signals via a network. A synchronization apparatus (20) of the invention receives synchronization signals transmitted from a synchronization signal source (10) via a network. The synchronization apparatus (20) comprises: a frequency synchronization unit (21) that performs, on the basis of a received synchronization signal, a frequency synchronization to output a frequency synchronization signal; a phase synchronization unit (23) that performs, on the basis of a synchronization signal transmitted from the synchronization signal source (10) via the network, a phase synchronization to output a phase synchronization signal; and a phase synchronization control unit (22) that uses a phase difference between the frequency synchronization signal and the phase synchronization signal to generate an offset value and that uses the offset value to modify the phase of the frequency synchronization signal.
