Abstract
Système de détection et de correction d'erreurs utilisant un polynôme de localisation d'erreurs sigma (x) et des syndromes d'erreurs Si . Un décodeur détermine si So Not= 0 et S2 + sigma S1 =0 et S3 + sigma S2 =0 lorsque sigma =S1 /S0 pour signaler qu'une erreur simple s'est produite dans un mot. S'il ne s'agit pas d'une erreur simple, le décodeur détermine s'il s'agit d'une erreur double et si tel n'est pas le cas détermine la présence éventuelle de trois ou de plus de trois erreurs. L'invention rend les détecteurs d'erreurs plus simples et plus rapide.
