ABSTRACT:
Various embodiments implement distributed block coding (DBC). DBC can be used for, among other things, distributed forward error correction (DFEC) of source data in communication systems or parity backup for error correction of source data in storage systems where the source data may be corrupted by burst errors. A distributed block encoder (DBE) encodes sequential source data symbols with a plurality of sequential block encoders to produce interleaved parity codewords. The interleaved parity codewords enable decoding of error-corrected source data symbols with a distributed block decoder (DBD) that utilizes a plurality of sequential block decoders to produce the error-corrected source data symbols. A distributed register block encoder (DRBE) and a distributed register block decoder (DRBD) can each be implemented in a single block encoder and a single block decoder, respectively, by using a distributed register arrangement.
