  • Abstract
    In this paper, we propose a method for avoiding high error floors of low-density parity-check (LDPC) codes for broadcasting systems. Harmful trapping sets which may introduce high error floors are investigated and removed by using the proposed method. Applying this method, the error floor of a DVB-S2 LDPC code is dramatically lowered by modifying only two numbers in its sequence representation.
