PURPOSE:To realize the mobile station radio equipment in which clock synchronization is early established in a base station with respect to an incoming burst signal from a mobile station in the digital mobile communication system. CONSTITUTION:A mobile station radio equipment 2 is provided with an electric field strength detector 14 and the distance between the base station radio equipment 1 and the mobile station radio equipment 2 is estimated by the detection value and a variable delay device 11 applies phase correction proportional to the distance to a recovery reference clock (b) to make the phase between the comparison reference clock (e) and the phase of the reception reference clock (d) coincident with each other. Thus, even when the mobile station is resident in any location in the service area, the clock synchronization is established quickly with respect to the incoming burst signal. |
