Abstract
A method for finding a valid codeword based on a near codeword trapping in a low-density parity-check decoding process includes identifying trapping set configurations and applying corrections to produce trapping sets with a limited number of invalid checks. Trapping set configurations are corrected in order to produce a trapping set in a table of trapping sets, the table associating each corrected trapping set with a valid codeword.
