Jingli Lin, Long-jiang Jing, Weile Zhu, Chen Yang · 2006
Based on some characteristics of decoding and error-floors of low-density parity-check (LDPC) codes, an approach of adding sum-check blocks to original LDPC blocks over GF(2) is proposed. The performance of this approach is analyzed and the circuits are also presented. Also, the simulation results show that the performance of the constructed LDPC codes can be improved significantly with low cost, as the block error probability (BEP) drops
