PEGIPEGI）算法来实现进一步的性能提升。-A novel construction for irregular low-density
parity-check (LDPC) codes based on a modification of the
Progressive Edge Growth (PEG) algorithm is presented. Edge
placement of the PEG algorithm is enhanced by use of the Sum-
Product algorithm in the design of the parity-check matrix. The
proposed algorithm is highly flexible in block length and rate.
The codes constructed by the proposed methods are tested in the
AWGN channel and significant performance improvements are
achieved. The flexibility of the proposed decoder optimisation
operation is then shown by its use in modifying the Improved
PEG (IPEG) algorithm to achieve further performance gains. Platform: |
