The device for data transmission comprises a coder with turbo codes, that is a turbocoder (22) containing an interleaver, a circuit (24) for puncturing the coded series which is reset at the start of each block of interleaving, a circuit (26) for elaborating symbols on the basis of data and redundancy bits (D,Y1,Y2) delivered by the turbocoder, a circuit (28) for inserting a synchronization sequence into the series of symbols with the location as a relation of predetermined position with respect to the elaborated symbols, which is carried out by the use of coded bits associated with the same block of interleaving, and a modulator (30). Independent claims are included for: (1) a method for transmitting data (2) a method for decoding data
