• A hard-decision iterative decoding scheme for the Davey–MacKay construction with symbol-level inner decoder is presented. In this scheme, the synchronisation capability of the inner decoder is enhanced by replacing the equal priori probabilities for symbols by the accurate hard-decision feedback information from the outer decoder. Furthermore, the error-correcting capability of the outer decoder is improved and the hard-decision feedback information is updated. Simulation results show that the presented scheme significantly improves the performance and saves the computational time with little performance loss.
