Abstract

''PROCESSO PARA DECODIFICAR UMA PALAVRA CóDIGO CìCLICA, E, DECODIFICADOR DE CóDIGO DE DISPARO''. Um decodificador de captura de erro (10) é provido, o qual executa mudanças cíclicas à direita de uma palavra código abreviada recebida em um registrador de mudança de decodificação (12), Conseq³entemente, a porção de lampejo de errro da palavra código recebida é encontrada no registrador (12) dentro do comprimento do código abreviado. Em outras palavras, o número de mudança cíclicas à direita necessário pelo registrador de mudança (12) para encontrar a porção de lampejo de erro da palavra recebida é da ordem de comprimento da palavra abreviada.
