<p>PURPOSE:To revise a burst length to be sent in response to the information transmission quantity by each earth station by generating an aperture signal for a data burst signal incoming next based on burst length information fetched in a data burst signal. CONSTITUTION:A gate signal generating section 4 receives a gate signal generating timing signal E2 and outputs a gate signal as a succeeding data burst aperture signal F2. A burst length information 'b' in a 2nd data burst signal DB2 is detected by using a detection timing signal H2 obtained through the use of the signal F2, a counter section 3 fetches it and counts down it, and a gate signal generating timing signal E3 for a 3rd data burst signal DB3 and an aperture signal F3 are obtained. Then they, a reference station burst signal and a head data burst signal use aperture signal B from a reception timing generating section 1 are ORed by an OR gate 7, from which an incoming burst signal aperture signal G is outputted. Thus, the data burst length is optionally changed.</p> |
