ABSTRACT:
A burst data transmitter by using an FIT sync signal transmitted from a district center to allow plural end offices to transmit burst data to the district center by means of an assigned slot using the FIT signal as a reference is applied to all end offices that transmit the slot assigned from the district center during the data transmission by a satellite, and a method therefor constructs the centrally-controlled Star system which decreases the frequency of error occurrence and shortens a recovery time in case of occurring the error by reinforcing a simple data transmission function of various communication systems for transmitting/receiving data by a satellite such as the VSAT system being a sub-miniature end earth station system that spends too much error-recovery time once an error occurs during the data transmission/reception. Thus, the sync signal in the data transmitted from the district center to the end office is simply extracted to be utilized to transmit the data, so that a separate sync channel is not required to thereby obtain an economical effect.
