Title
Decoder Optimised Progressive Edge Growth Algorithm
Abstract
A novel construction for irregular low density parity check (LDPC) codes based on a modification of the Progressive Edge Growth (PEG) algorithm is presented. The edge placement procedure of the PEG algorithm is enhanced by the use of the Sum-Product decoder in the design of the parity-check matrix. The proposed algorithm, like the PEG algorithm, is highly flexible in block length and rate. The codes constructed by the methods presented are tested in the AWGN channel and significant performance improvements are achieved. The flexibility of the proposed decoder optimisation operation in its application to PEG-based construction methods is then demonstrated by its use in modifying the Improved PEG (IPEG) extension to the PEG algorithm to achieve further performance gains.
