Semi-random LDPC codes with efficient encoding
Xueqin Jiang, M.H. Lee · Electronics Letters · 2009
An approach to construct semi-random low-density parity-check (SR-LDPC) codes is introduced. These codes are designed with the progressive edge-growth algorithm and can be encoded with only multiple parity-check encoders and interleavers. Therefore, the proposed codes have large girth and efficient encoding. Simulation results show that the codes perform very well over the AWGN channel with iterative decoding.
