Method and system for synchronization for DVB-S2 frame and its associated frame structure

摘要

A communication system using the DVB-S2 standard, and its associated frame structure, comprises at least two users Ui, characterized in that the super-frame ST1 associated with the first user U1 is composed of at least one frame T1 each 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, the super-frame ST2 associated with the second user U2 is composed of one or more frames T2 each 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, the system comprises a module NCC adapted for determining the number d1 and the number d2 of dummies to be introduced so that the temporal duration of ST2 is equal to the temporal duration of ST1.

1. A communication system using the DVB-S2 standard, the system comprising:
a first transceiver U1 and a second transceiver U2, wherein: a first super-frame ST1 associated with the first transceiver U1 comprises:
at least one first frame T1 comprising at least one first header and a first data part, anda number d1 of first dummy variable size frames comprising s1 slots, a second super-frame ST2 associated with the second transceiver U2 comprises:at least one second frame T2 comprising at least one second header and a second data part, anda number d2 of second dummy variable size frames comprising s2 slots; a controller configured to determine the number d1 of the first dummy variable size frames within the first super-frame ST1 and the number d2 of the second dummy variable size frames within the second super-frame ST2 so that a second temporal duration of the second super-frame ST2 is equal to a first temporal duration of the first super-frame ST1; and k transceivers Uk and k super-frames STk based on a minimum band B of the communication system, wherein the super-frames STk of band nB are determined by multiplying n by a number of frames per super-frame of the minimum band B, where k is a positive integer greater than or equal to two and n is a positive integer greater than zero that depends on time.
