  • Abstract
    In this letter, we propose a fast and accurate technique to estimate the error floor of variable-regular low-density parity-check (LDPC) codes under quantized iterative decoding algorithms. The technique, which is based on enumerating the dominant elementary trapping sets of the code, provides significant improvement over existing methods in terms of speed and accuracy.
