Abstract

Patente de Invenção: <B>"PROCESSO PARA A REGENERAçãO DE DADOS"<D>. No processo para a regeneração de dados são transmitidos dados protegidos. Do lado de recepção é determinada a taxa de falha do sinal de recepção (DS). Os instantes de exploração e os limiares de decisão são variados em uma faixa predeterminada e, a partir das falhas de transmissão determinadas durante esta operação, é ajustado um instante de exploração ótimo (T, ìndice A) e um limiar de decisão ótimo (O) no (AB). Em virtude da correção de falha não se expressam falhas de transmissão adicionais.
