Integrated block codes encoder-decoder

摘要

Increasing needs in digital communications through poor quality channels lead to protect information by the use ofuderrors erasures detection/correction codes . These errata may be randomly scattered or packed into short blocks :udthis fact can be exploited by the coding scheme itselfudThe encoder/decoder that we describe here can process as well BCH as Reed-Solomon codes ; their sizes and errorcorrectingudcapabilities are user-defined parameters .udMoreover, for BCH codes, it is possible to repeat R times each of the transmitted bits and make a weighte dudmajority decoding before BCH decoding.udThe device is to be a monolithic integrated circuit usable as an intelligent co-processor by a microprocessor. It canudwork independently after reception of the codes parameters. Its architecture is optimized for the repetitive andudspecific operations involved in the coding and decoding processes .
