A method and system of communication in a wide band high frequency HF communication system is disclosed. The system includes at least n communication channels, an interleaver common to the n communication channels, a means for determining the quality of communication of each of the n communication channels. At least the following information is introduced into the structure of the frame of the data at the level of an autobaud: an item of information about the modulation employed on each of the n communication channels ch, an item of information about the interlever common to the n communication channels, the corrector code FEC employed, the number of communication channels employed (n) as well as for each one its identifier id. The modulation is chosen on channel n, a common coding and interleaving are operated on the n channels, and the information introduced in the shared autobaud is transmitted.
