摘要：
A method for scrambling a communication system (EM,REC) consisting of generating, in a signal (S) intended to be transmitted by one or a plurality of transmitters (EM_B1, EM_B2,...,EM_B3) compatible with said communication system (EM,REC), at least one dummy sequence (SYNC
F ), said method being characterised in that it comprises the following steps: - Defining said dummy sequence (SYNCF) and the time and/or frequency position thereof within the signal (S) to be transmitted, - Estimating the value and the position of the dummy bits (BF) to be inserted into the data sequence (Du,T) to be transmitted at the input of the transmission chain or a sub-part of the transmission chain so as to obtain, in the sequence produced at the output of the transmission chain, the predefined value and time position of the symbols of said dummy sequence (SYNCF), - Inserting the dummy bits (BF) into said data sequence (Du,T), in the obtained positions.
