- Description
- This study considers the optimisation of multi-edge type low-density parity-check (MET-LDPC) codes to maximise the decoding threshold. The authors propose an algorithm to jointly optimise the node degree distribution and the multi-edge structure of MET-LDPC codes for given values of the maximum number of edge-types and maximum node degrees. This joint optimisation is particularly important for MET-LDPC codes as it is not clear a priori which structures will be good. Using several examples, they demonstrate that the MET-LDPC codes designed by the proposed joint optimisation algorithm exhibit improved decoding thresholds compared with previously reported MET-LDPC codes.
