Abstract: Provided is a communication repeater including a receiver configured to receive a plurality of test signals from a plurality of external communication devices and then receive a plurality of downlink signals from the plurality of external communication devices, and a digital signal processor configured to measure a delay time of each of the plurality of test signals and perform a delay synchronization process for the plurality of downlink signals, wherein the digital signal processor is configured to determine whether the plurality of downlink signals for which the delay synchronization process has been performed are synchronized, and perform synchronization restoration for a downlink signal having a synchronization error among the plurality of downlink signals, based on a result of the determining.
