Abstract
A method is provided for synchronizing a receiver receiving a signal corresponding to successive samples arranged in a frame with the beginning of the frame being defined by a preamble having a repetition of a first sequence of L samples coming from a transmitter. A method of transmitting the signal is also provided. The preamble is made up of two portions, one portion constituted by the first repeated sequence and another portion constituted by a second repeated sequence. The second sequence corresponds to the symmetrical version of the first sequence limited to a number M of samples that is less than the number L of samples.
