Abstract
A method of synchronising a communication signal entering into a receiver. Each frame of the signal includes a learning symbol formed of N repetitions of a learning sequence. The method includes the determination of a total correlation signal by correlating the input signal with a correlation symbol formed of N repetitions of a correlation sequence corresponding to all or part of the learning sequence and duration t, and the determination of a partial correlation signal by correlating the input signal with the correlation sequence. A peak of the total correlation signal is identified at an instant t. At least one threshold is defined from the power of the peak of the total correlation signal, and the power of the partial correlation signal is compared here to the instants t−k*t, with k a whole number between 0 and N−1.
