Abstract:
1. A method for selecting a LDPC code in a data communication apparatus comprising: receiving a word generated using a LDPC code; analyzing the word to determine if the word includes a first feature indicative of a first known impact on error probability; analyzing the word to determine if the word includes a second feature indicative of a second known impact on error probability; determining an estimated error probability associated with the LDPC code based on the first feature and the second feature without decoding an encoded word; classifying the LDPC code into one of a plurality of LDPC code classifications, each of the plurality of LDPC code classifications associate with an estimated error probability; ordering the LDPC code classifications based on the estimated error probability; and selecting a LDPC code from the plurality of ordered LDPC code classifications for use by a data communication apparatus based on the estimated error probability.
