Abstract
The disclosure relates to a method of synchronising a device for receiving scrambled data, using at least one periodic scrambling sequence which is divided into K time intervals, each interval comprising N bit periods known as symbols. In particular, one such method includes calculating a synchronisation value of at least one polynomial that generates the aforementioned scrambling sequence within a pre-determined synchronisation time interval and synchronisation bit period. During the calculation step, the sequence is progressed through at increments of at least one time interval and at least one bit period, using a matrix calculation of the synchronisation value.
