Abstract
Method and system for coding/decoding a digital data stream coded with bitwise interleaving in multiple transmission and reception for a radio interface, in which the coding includes subjecting an initial digital data stream to an outer coding, an interleaving, a layer demultiplexing on multiple pathways, converting by modulation successive bits of each layer into Qm-ary symbol then transmitting each symbol by means of a transmission antenna of an array of antennas and the decoding includes receiving the digital data stream transmitted on multiple r reception antennas forming an array, subjecting the set of symbols received to an iterative process of equalization and joint multilayer detection, on the basis of an a priori information item, subjecting the first extrinsic information stream obtained to a deinterleaving, subjecting a second extrinsic information stream obtained to an outer decoding and a third extrinsic information stream obtained to an interleaving so as to generate the a priori information item and reinjecting the latter into the process.
