COMMUNICATION CHANNEL WITH REED-SOLOMON ENCODING AND SINGLE PARITY CHECK

摘要

A COMMUNICATION CHANNEL INCLUDING REED-SOLOMON (RS) AND SINGLE-PARITY- CHECK (SPC) ENCODING/DECODING. MULTIPLE RS CODEWORDS ARE COMBINED AND THEN SPC ENCODED INTO AN RS/SPC ARRAY. A SOFT-INPUT SOFT-OUTPUT (SISO) CHANNEL DETECTOR (172) DETECTS THE RS/SPC ENCODED BITS AND PROVIDES SOFT (RELIABILITY) INFORMATION (180) ON THESE BITS. A COMBINED RS AND SPC ERROR CORRECTION BLOCK (706) PROVIDES A RECOVERED USER OUTPUT. AN ITERATIVE SOFT INPUT DECODING ALGORITHM COMBINES RS AND SPC ERROR CORRECTION.
