Abstract

Patente de Invenção:<B>"PROCESSO E DISPOSIçãO PARA A REGULAGEM DO LIMIAR DE DECISãO E DO INSTANTE DE EXPLORAçãO DE UM REGENERADOR DE DADO"<D>. O regenerador de dado apresenta um segundo ramo de dado, cujo limiar de decisão pode ser deslocado. Por meio da comparação dos dados de saída, podem ser determinadas as falhas de bit, as quais são produzidas por meio de um deslocamento do limiar de decisão. Por meio do deslocamento por tentativas do instante de exploração e subseq³ente deslocamento do limiar de decisão são encontrados o instante de exploração ótimo e o limiar de decisão ótimo.
