Abstract: A method of communication, on a radio channel, between at least two nodes is disclosed. This method is adapted for emitting on the channel in an alternating manner, comprising formulating, by one of the two nodes, termed the emitter, a signal comprising a preamble comprising a series of frames, followed by the data frame, at least one first frame of the preamble comprising a copy of the data frame and indicating a number of frames of the preamble separating this first frame from the data frame and emitting, by the emitter node, of the signal thus formulated on the radio channel.

Abstract: Method of communication, on a radio channel, between at least two nodes (2) adapted for emitting on the said channel in an alternating manner, comprising the following steps, with a view to transmitting a data frame: formulation, by one of the two nodes, termed the emitter, of a signal (S) comprising a preamble comprising a series of frames, followed by the data frame, at least one first frame of the preamble comprising a copy of the data frame and indicating a number of frames of the preamble separating this first frame from the data frame; emission, by the emitter node, of the signal thus formulated on the radio channel.
