<p>PURPOSE:To improve the transmission efficiency of a data by estimating a phase of a recovered carrier and a phase of a recovered clock signal at the prescribed point of time of a succeeding burst from those at the prescribed point of time of a burst during reception so as to establish the synchronization. CONSTITUTION:A receiver 4 estimate the phase of a carrier at a head point of time of a succeeding burst and the phase of a clock signal at the head point of time for a BTR period based on the phase of a reference carrier and the phase of a clock signal recovered at a carrier recovery section 47 and a clock recovery section 48 at a point of time when a unique work(UW) of a current burst is detected. Then the synchronization is established so that the phase of the reference carrier and the phase of the clock signal at the reception of a succeeding burst are equal to the estimated phase of the carrier and of the clock signal. Thus, the synchronization is established by the receiver 4 according to the estimated carrier phase and clock phase after the synchronization is accurately established.</p> |
