摘要：Method of correcting a message to be transmitted between a sendingapparatus and a receiving apparatus distributed on a transmission line powered by themains, the said line being the seat of interference affecting the transmission of the saidmessage. According to the invention, the said method of correction includes the

following steps: a) sending by the sending apparatus, at a first transmission speed (V1), ofthe message with a request for acknowledgement, b) in the absence of

acknowledgement, sending by the sending apparatus, at another transmission speed, of acorrection message synchronous with the frequency of the mains, with a request foracknowledgement, and containing a correction algorithm, then, the correction algorithmbeing equal to the identity algorithm, c) in the presence of an acknowledgement of thecorrection message, sending by the sending apparatus, at the said other speed, of themessage with request for acknowledgement, d) in the absence of an acknowledgementof the correction message, sending by the sending apparatus, with yet anothertransmission configuration, of the message with request for acknowledgement.
