Frame synchronisation in a receiver by using a preamble having a specific structure
Résumé
The invention relates to a method for synchronising a receiver receiving a signal corresponding to consecutive samples arranged in frames, the start of which is defined by a preamble including the repetition of a first sequence of L samples from a transmitter as well as a method for transmitting the signal. According to the invention, the preamble consists of two portions, one portion made up of the first repeated sequence and another portion made up of a second repeated sequence, the second sequence corresponding to the symmetric version of the first sequence limited to a number M of samples lower than the number L of samples.
