METHOD FOR TRANSMITTING A DIGITAL SIGNAL FOR A MARC SYSTEM WITH MULTIPLE DYNAMIC HALF-DUPLEX RELAYS, PROGRAM PRODUCT AND CORRESPONDING RELAY DEVICE

摘要

The invention relates to a relaying method implemented by a half-duplex relay for a telecommunication system comprising several sources, the half-duplex relay and at least one other relay and a recipient. The method comprises: a phase of receiving code words transmitted by the sources during N uses of the transmission channel, the successive codewords transmitted by a source corresponding to B blocks whose first block can be decoded independently of the others; blocks, comprising a decoding step for estimating by source from received code words a message associated with the code words (cs) transmitted by the source, - an error detection and decoding step by the relay of the decoded messages without errors and - a coding phase and transmission to the receiver of a signal representative of the only error-free decoded messages including channel coding by means of an incremental redundancy code to obtain a coded channel code word, such as the relay goes from a non-selective reception to a selective reception after the reception of B1 blocks and toggles from the reception phase to the coding and paging phase. s control of the decision step, 1 ≤ B1 B.
