    Abstract: Some embodiments relate to a full-duplex relay for a telecommunications system comprising a plurality of sources, the relay, and a destination. The relay comprises a decoder which estimates for each source a code word xS,t encoding a K-bit message uS,t, from received blocks corresponding to successive code words xS,t transmitted simultaneously by the sources during T time slots, such that at each time slot t, t=1, . . . , T, a code word xS,t comprises B blocks xS,t(1), xS,t(2), . . . , xS,t(B) of which the first can be decoded independently of the other blocks. It also comprises a decision component which enables the relay to detect messages that have been decoded without error and to take a decision and an encoder and transmitter which encode a signal and transmit it to the destination, which signal is representative only of messages that have been decoded without error. After each received block, the encoding and transmission unit is under the control of the decision component.

    Abstract: A relaying method performed by a half duplex relay for a telecommunications system. The method includes a reception stage of receiving codewords transmitted by a source, the successive codewords corresponding 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 message being associated with the codewords transmitted by the source. The relay performs an error detection and decision-taking step on messages that are decoded without error. The relay encodes a signal and forwards it to the destination, wherein the signal is representative of only those messages that are decoded without error, such that 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 error detection and decision stage.

    Abstract: A method for relaying messages via a half-duplex relay for a telecommunications system with M sources, L relays and a destination, where M>1, L≥1, according to an orthogonal multiple access scheme of the transmission channel between the L relays and the destination. The method includes: decoding, via a relay, M messages each being associated with a frame and coming from a source among the M sources with detection of errors on the messages; transmitting from the relay to the destination a signal representative of a least one portion of a set of the messages for which no errors have been detected by the relay conditional on authorization from the destination, transmitting from the relay to the destination of a monitoring signal indicating a set of messages for which no errors have been detected by this relay, this transmission of the monitoring signal occurring before the transmission of the representative signal.

    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: One embodiment described herein relates to a method of predicting the performance of a communication system on a transmission channel. The system may comprise a transmitter suitable for applying bit interleaved coded modulation to information bits issued by a source to generate coded symbols, these coded symbols being transmitted by the transmitter over the transmission channel. The coded modulation may be based on a turbo-code comprising at least two constituent codes. The system may also comprise an iterative receiver, suitable for performing an iterative interference cancellation technique to process the coded symbols received from the transmission channel, the iterative receiver comprising an equalizer, a demodulator, and a turbo-decoder that are activated during each iteration performed by the iterative receiver. The turbo-decoder may comprise at least two decoders suitable for decoding the respective constituent codes of the turbo-code, the decoders being suitable for interchanging probabilistic quantities in an iterative manner.
