Abstract: A full-duplex relay and method of a telecommunication system having several sources, at least the relay and a recipient. The relay includes: a decoder estimating a message for each source, from successive received blocks transmitted during a current interval by a source, a decision module deciding which source messages were decoded without error from the estimated messages, a network encoder encoding a selection of the messages decoded without error and a transmitter transmitting a signal representative of the network encoded messages to the destination and a control signal indicating the selected messages. The decision module selects messages decoded without error at the input of the network encoder by only considering a return path from the destination indicating correct or incorrect decoding of messages. After each reception of a block, the decision module prevents the emission by the transmitter for a time period necessary to receive and decode the return path.

Abstract: A method and relay for relaying messages. The relay includes tests reliability relating solely to messages estimated with error and taken in their form prior to error detection in order to be able to separate messages that are reliable and messages that are not reliable. The relay also includes a shaper unit having a channel interleaver and a modulator taking account only of the messages estimated without error and of those messages estimated with error that are reliable, this shaping being performed in soft form if at least one message estimated with error successfully passes the reliability test.

Abstract: A relaying method in a telecommunication system having a plurality of sources, a half-duplex relay and a recipient. The relay performs a receiving phase of: receiving codewords transmitted by the sources, including estimating for each source a message associated with the codewords transmitted by the source, error detection and decision of error-free decoded messages, which determine the set of sources decoded without error by the relay; a phase of coding and transmitting to the recipient a signal uniquely representative of the selection of messages, such that, after each reception of a block from different sources, the relay receives and decodes a return path from the destination indicating if no or at least one message is decoded without error, these messages determining the set of sources decoded without error. The relay switches from the receiving phase to the coding and transmission phase once a logic rule is valid.

Abstract: A relay for a telecommunications system comprises a decoder which responds to received blocks corresponding to successive code words xS,t transmitted simultaneously by sources during T time slots. At each slot t, t=1, . . . , T, a code word xS,t comprises B blocks xS,t(1), xS,t(2), . . . , xS,t(B). The first can be decoded independently of the other blocks, to estimate for each source code words xS,t. It also comprises a detector which detects messages that have been decoded without error and takes a decision and an encoder and transmitter which encodes a signal and transmits it to the destination, which signal is representative only of messages that have been decoded without error. When estimating, the decoder takes account of a signal transmitted by another relay representative of messages from the sources that were decoded without error by that relay. The encoder and transmitter is under the control of the detector in accordance with a selection scheme, after each received block.

Abstract: A relaying method performed by a half-duplex relay for a telecommunications system includes a reception stage of receiving codewords from sources during N uses of the transmission channel. The successive codewords correspond to B blocks, the first of which can be decoded independently of the other blocks. This stage includes a decoding step of estimating a message from each source based on received codewords. The relay performs an error detection and decision-taking step on messages decoded without error. The relay performs a stage of encoding a signal and forwarding it to a destination. The signal is representative of only messages decoded without error and includes channel encoding by an incremental redundancy code to obtain a channel encoded codeword. The relay passes from non-selective reception to selective reception after receiving B1 blocks and switches from the reception stage to the encoding and forwarding stage under control of the decision step.
