ABSTRACT:
The disclosure relates to the transmission of information by packets on carrier frequencies, with data spreading and compression, between several transmitters and at least one receiver of one and the same communications network. In the network, the packets are constituted by a header followed by sub-packets transmitted in synchronism with the header and with a given periodicity, and this synchronism and this periodicity are the same for all the packets. Furthermore, all the sub-packets have the same structure as a standard sub-packet formed by mutually orthogonal segments. With such packets, the risks of overlapping are notably smaller than they were with standard packets. Application to the transmission of packets.
