Abstract:
1. A radio apparatus comprising: a first reception unit configured to receive a first signal from a first radio apparatus controller; a first synchronous clock generation unit configured to generate a first recovery clock from a clock component included in the first signal received by the reception unit; a second reception unit configured to receive a second signal from a second radio apparatus controller; a second synchronous clock generation unit configured to generate a second recovery clock from a clock component included in the second signal received by the reception unit; a clock synchronization detection unit configured to detect whether or not the second recovery clock is synchronous with the first recovery clock; a code selection unit configured to select a code indicating whether or not the second recovery clock is synchronized with the first recovery clock according to a detection result of the synchronization detection unit; a signal processing unit configured to generate a third signal to which the code selected by the code selection unit is added and which is synchronous with the first recovery clock; and a transmission unit configured to transmit the third signal generated by the signal processing unit to the second radio apparatus controller.
