ABSTRACT:
The disclosure relates to the transmission of data by packets on carrier frequencies with spreading and de-spreading of the data elements. In order to reduce the risks of overlapping among packets sent out by different transmitters, each packet to be transmitted is designed according to the characteristics of frequency spreading and/or code spreading of a common standard packet, constituted by successive segments all orthogonal to one another, the first segment comprising a header designed for identification. At reception the header, when it is found, activates the processing of the corresponding packet with de-spreading as a function of the characteristics of the spreading of the standard packet as they are known to the transmitter.
