Abstract
Patente de invenção: <B>"PROCESSO DE DISPOSITIVO PARA TRANSMISSãO DE INFORMAçõES ATRAVéS DE LINHAS DE ABASTECIMENTO DE CORRENTE"<D>. A invenção descreve um processo e sistema para a comunicação de dados rápida e livre de interferências através de redes de abastecimento de energia em quaisquer planos de tensão. O efeito combinado de interferências por distorção de sinais, enfraquecimento ou ruído dos sinais seletivos de freq³ência e por interferências de impulsos é diminuído pelo uso de um processo de modulação de portadores múltiplos-MCM. Pela combinação do processo de MCM com um intercalador (interleaver) (intermisturador de dados) especialmente adaptado e uma codificação de proteção contra erros, os índices de erros podem ser drasticamente reduzidos e as velocidades de transmissão aumentadas nitidamente para acima de 2 kbits/s.
