Abstract
Disclosed is a method for transmitting messages between a transmitter and a receiver on a channel on which noise may be present. The messages are constituted by a sequence of data and comprise an initial portion (header) containing data to allow recognition of the message, a central portion (body) containing the valid message to transmit and an end portion (tail) containing information to verify the completeness of the message. The method consists in inserting in the message header a signature obtained from the combination of a first fixed part and of a second validation part; and recognizing a valid message received by verifying whether the fixed part of the message received generates the same validation part.
