Abstract :
In this paper, the design of low-density parity-check (LDPC) codes for binary erasure channels (BEC) with less number of decoding iterations in the parallel message-passing decoding is presented. We consider only the cases where the capacity is approached with sufficiently low parity-check matrix density.
