METHOD FOR TRANSMITTING A DIGITAL SIGNAL FOR A MARC SYSTEM WITH A FULL-DUPLEX RELAY, AND CORRESPONDING PROGRAM PRODUCT AND RELAY DEVICE

摘要

The invention relates to a method for transmitting a digital signal to a network with at least four nodes comprising two transmitters, a relay and a receiver, separated from one another by non-orthogonal links using a spatially distributed network code. The method includes the following steps: a step (2) comprising encoding by transmitter, delivering a code word per block of K data bits; a step (3) comprising the transmission in the two transmitters respectively of two code words, over N transmission intervals; a step (4) comprising combined iterative detection/decoding in the relay, in order to separate the flux originating from the two transmitters and to determine, for each flux, a vector representative of the code word received; a step (5) comprising the combined encoding in the relay of the two vectors originating respectively from two code words transmitted over N transmission intervals; a step (6) comprising the transmission by the relay of a redundancy datum over N transmission intervals; and providing an order in the relay such that the redundancy datum transmitted over N transmission intervals corresponds to the code words transmitted over the N preceding transmission intervals.
