摘要： Method for processing a sequence of digital signal samples comprising a first sub-sequence and a second sub-sequence, said method comprising: forming (106) a first block of samples comprising the first sub-sequence and a second block of samples comprising header samples followed by the second sub-sequence; demodulating (108) the first block of samples through a digital demodulator to produce a first block of symbols, and the second block of digital signal samples through a second digital demodulator to produce a second block of symbols, the second demodulator implementing a carrier synchronisation or symbol rate synchronisation starting with the header samples (E6-E9), which comprise samples in a number adapted in such a way that the synchronisation is effective before the second demodulator demodulates the second sub-sequence; and reconstructing (114) a sequence of symbols by concatenating the first symbol block with the second symbol block.
