Abstract
A method for non-orthogonal transmission of a signal intended for a system with N sources, M relays and a single receiver, in which simultaneous transmission over a single spectral resource by the relays is simultaneous with a transmission over a single spectral resource by the sources. The method includes, for each relay: joint iterative detection/decoding of messages transmitted respectively by the sources during first transmission intervals to obtain decoded messages; detecting errors on the decoded messages; interleaving the detected error-free messages, followed by algebraic network coding including a linear combination, in a finite field of an order higher than two, of the interleaved messages to obtain a coded message, the linear combinations being independent, in pairs, between the relays; and channel coding to generate a signal representative of the network coded message and to transmit this signal during the subsequent transmission intervals simultaneously with a transmission by the sources.
