- Abstract
- In this paper, we propose a construction method of rate-compatible block-type low-density paritycheck (RC B-LDPC) codes using extending and puncturing, which works well over a wide range of code rates by decreasing the amount of puncturing nodes to mitigate the performance degradation at high rate range. RC B-LDPC code constructed by the proposed scheme to achieve the target code rates from 1/3 to 4/5 results in good frame error rate (FER) performance, even better than the well-designed rate-1/3 code in the small number of iterations (say, < 20).
