Abstract
In this work, a novel design method of DP-LDPC codes for the JSCC system via the ACE-PEG algorithm has been proposed. The designed base matrix contains more higher-degree VNs than the conventional ones, and thus increases the amount of message between the cycles and/or stopping sets and the remaining part of the Tanner graph via the ACE-PEG algorithm. Simulation results have demonstrated that the proposed design approach of DP-LDPC codes obtains significant performance enhancement in both waterfall and error-floor regions compared to the selected benchmark schemes from the latest literature.
