Abstract

PURPOSE:To eliminate a circuit breakdown due to the discontinuity of a carrier phase on a device used for the intermittent communication system, by providing a signal detector which detects the arrival of an intermittent signal and by varying the connection of an input from each antenna of a diversity device while the detector detects the intermittent signal.
