<p>A LDPC erasure correcting method is provided by the invention. The method includes: setting the every erasure bit in the received codeword to the value in GF(2) which has only two elements, thus generating the first codeword to be decoded; then setting the every erasure bit in the received codeword to the reverse of the set bits in the first codeword to be decoded, thus generating the second codeword to be decoded; executing the hard decoding of the first codeword and the second codeword and then getting the decoding result of the hard decoding; finally determining the result of the erasure correcting decoding based on the result of the hard decoding. A LDPC erasure correcting system and a computer readable storage medium carrying the LDPC erasure correcting program are additionally provided by the invention. The invention can complete the LDPC erasure correcting decoding for the BEC, and improves the ability to correcting the errors in the BEC transmission.</p> |
