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.
