Abstract

"PROCESSO E DISPOSITIVO PARA CODIFICAR E DECODIFICAR INFORMAçãO DE MúLTIPLAS PALAVRAS E PORTADOR DE ARMAZENAMENTO UNITáRIO". Informação de múltiplas palavras é baseada em símbolos de multibit dispostos em relativa contig³idade em relação a um meio, e é codificada com um entrelaçamento em modo de palavra e código de proteção de erro em modo de palavra para prover chaves de localização de erro através de grupos de múltiplas palavras. Em particular, as chaves originam-se em palavras-chaves de alta proteção (BIS) que são entrelaçadas entre colunas-chaves, e também em colunas de sincronização constituídas se grupos de bit de sincronização.As colunas de sincronização são localizadas onde as colunas-chaves são dispostas relativamente de modo mais escasso. As chaves são direcionadas a palavras-alvos de baixa proteção (LDS) que são entrelaçadas de uma maneira substancialmente uniforme entre colunas-alvos que formam grupos de colunas de tamanho uniforme entre arranjos periódicos de colunas-chaves e colunas de sincronização.
