Method and system for synchronization for dvb-s2 frame and its associated frame structure

A method for constructing a super-frame intended to be used in a system using the DVB-S2 standard comprising at least two users U1, U2, a management and control means wherein it comprises at least the following steps:

• defining a first super-frame ST1 associated with a first user U1 composed of at least one header, of a data part, the said super-frame ST1 comprising a number d1 of “dummy” variable size frames consisting of s1 slots,
• defining a second super-frame ST2 associated with a second user U2 composed of at least one header, of a data part, the said super-frame ST2 comprising a number d2 of “dummy” variable size frames consisting of s2 slots,
• determining the number d1 and the number d2 of dummy frames to be introduced so that the temporal duration of ST2 is equal to the temporal duration of ST1.

A frame structure used in communication systems using the DVB-S2 standard, comprising a number of frames and a number of “dummy” frames disposed so as to obtain a super-frame of fixed duration, the duration of the super-frame obtained is identical for several users in communication whatever the allocated frequency band.
