ERROR CORRECTION SYSTEM

摘要

The system uses an error location polynomial which is defined by double-correction. Bose-Chaudhri-Hocquenghem codes each consisting of elements of Galois field GF(2m). The polynomial calculator for decoding a Reed-Solomon code supplies reproduced symbols to a syndrome generator. The four generated sydromes are stored in RAM and read out to an arithmetic logic unit and three registers. Three parts of products of these syndromes taken two at a time are supplied to latch circuits and multiplying registers.
