Abstract :
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.
