摘要： Communication device employing LDPC (Low Density Parity Check) coding with Reed-Solomon (RS) and/or binary product coding. An LDPC code is concatenated with a RS code or a binary product code (e.g., using row and column encoding of matrix formatted bits) thereby generating coded bits for use in generating a signal that is suitable to be launched into a communication channel. Various ECCs/FECs may be employed including a BCH (Bose and Ray-Chaudhuri, and Hocquenghem) code, a Reed-Solomon (RS) code, an LDPC (Low Density Parity Check) code, etc. and various implementations of cyclic redundancy check (CRC) may accompany the product coding and/or additional ECC/FEC employed. The redundancy of such coded signals as generated using the principles herein are in the range of approximately 20% thereby providing a significant amount of redundancy and a high coding gain. Soft decision decoding may be performed on such coded signal generated herein.

摘要： Communication device employing binary product coding with selective additional cyclic redundancy check (CRC) therein. Product code encoding (e.g., employing row and column encoding of matrix formatted bits, selectively with interleaving and/or permutation of the bits therein) may be combined with additional error correction code (ECC) or forward error correction (FEC) coding thereby generating coded bits for use in generating a signal to be launched into a communication channel. Various ECCs/FECs may be employed including a BCH (Bose and Ray-Chaudhuri, and Hocquenghem) code, a Reed-Solomon (RS) code, an LDPC (Low Density Parity Check) code, etc. The redundancy of such coded signals as generated using the principles herein is in the range of approximately 7%, and hard decision decoding may be performed on such coded signals generated herein. In accordance with decoding such signals, various bit decisions (within certain iterations) may be selectively ignored and/or reverted back to previous bit decisions.
