摘要

PROBLEM TO BE SOLVED: To suppress reduction in synchronization accuracy even when an external reference signal cannot be received or a received external reference signal cannot be trusted.SOLUTION: A radio apparatus 2 synchronized with an external reference signal received externally comprises: a reception unit 21 for receiving the external reference signal; an error detection unit 22c for detecting a synchronization error on the basis of the external reference signal received by the reception unit 21; and a correction unit 22d for correcting the synchronization error detected by the error detection unit. When an external reference signal cannot be received or a received external reference signal cannot be trusted, the correction unit 22d executes a continuous correction mode in which correction is performed on the basis of a synchronization error detected by the error detection unit 22c in the past.
