Abstract
A method for semi-orthogonal transmission of a signal intended for a system with N sources, M relays and a single receiver whereby the simultaneous transmission on a same spectral resource by the relays is successive and not simultaneous to a simultaneous transmission on a same spectral resource by the sources. The includes, by relay: joint iterative detection/decoding of messages transmitted respectively by the sources to obtain decoded messages, detecting errors on the decoded messages, interleaving the detected messages without errors followed by algebraic network coding consisting of a linear combination in a finite group of an order strictly higher than two of the interleaved messages to obtain a coded message, the linear combinations being independent, two by two, between the relays of the system, and formatting including channel coding to generate a signal representative of the network coded message.
