Method and system of selective relaying in a communication network comprising a plurality of sources, a relay and a reception device with detection by the relay of errors on the received estimated messages and transmission, from the relay to the reception device, of a signal representative of only the messages for which no errors were detected.

摘要

The present invention relates to a method for selective relaying in a communication network including a plurality of sources, a relay, and a recipient, characterized in that the method comprises the following steps: receiving, via the relay, messages transmitted by the sources, respectively, so as to obtain an estimate of the messages; detecting, at the relay, errors on the estimated messages; and transmitting, from the relay to the recipient, a signal representative of single messages for which no error has been detected resulting from a non-bijective surjective function applied to the detected error-free messages including interleaving and encoding. The representative signal is transmitted by the relay to the recipient with a control signal indicating which messages are represented in the representative signal. The present invention also relates to a device for selective relaying in a communication network.
