Abstract:
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 (e.g., possibly by performing bit-flipping), various bit decisions (within certain iterations) may be selectively ignored and/or reverted back to previous bit decisions.
Abstract:
Disclosed herein are certain embodiments of a coding system and method that guarantee a pair of sync bits in a transcoded block will appear on the same physical lane. Embodiments may then use this property for data synchronization and to guarantee a bit transition in a certain amount of time on a physical lane. Embodiments of a coding system and process for configuring alignment marker blocks are also disclosed.
Abstract:
A data encoding circuit and a corresponding method is provided. The data encoding circuit includes a first data formatter in communication with an encoder section. The first data formatter is configured to receive blocks of source data in serial and output parallel two dimensional source data. The encoder receives the parallel two dimensional source data and that computes a plurality of serial row parity bits and a plurality of parallel column parity bits of an error correcting code from the parallel two dimensional source data. A second data formatter communicates with the encoder section and receives the parallel column parity bits and outputs serial column parity bits.
