We propose a class of Rate-compatible(RC) Low-density parity-check(LDPC) codes with a very wide range of code rates. To widen the range of rates, we have developed an optimal transmission scheme to push the upper boun...

A Layered dynamic scheduling (LDS) for Belief-propagation (BP) decoding of LDPC codes over GF(q) is presented, which is derived from the dynamic scheduling for the BP decoding of binary LDPC codes. In order to r...
Based on some characteristics of the decoding and the error floors of Low-density parity-check (LDPC) codes, an approach of adding single parity-check blocks to original LDPC blocks over GF(2) is proposed, which c...
To reduce the implementation complexity and mitigate the performance loss, an adaptive non- uniform quantized rain-sum approximation decoding for Low-density parity-check (LDPC) codes is proposed. The rain-sum appro...
