Abstract

"INDEXAçãO DE POSIçõES E SINAIS DE PULSO EM LIVROS DE CóDIGO ALGéBRICOS PARA CODIFICAçãO DE SINAIS DE BANDA LARGA". Trata-se de um método de indexação que compreende a formação de um conjunto de trilhas de posições de pulso, restringindo as posições dos pulsos de amplitude diferentes de zero das combinações do livro de código, de acordo com o conjunto de trilhas das posições de pulso, e indexando no livro de código cada pulso de amplitude diferente de zero das combinações de pelo menos em relação à posição da trilha correspondente, a amplitude do pulso, e o número de posições de pulso na dita trilha correspondente. Para indexar a(s) posição(ões) de um e dois pulso(s) de amplitude diferente(s) de zero, os procedimentos do pulso de código_1 do pulso de código_2 são usados respectivamente. Quando as posições de um número X de pulsos de amplitude diferente de zero são situadas em uma trilha, X<242>3, os subíndices desses pulsos são calculados usando os procedimentos de pulso de código_1 e pulso de código_2, e o índice global é calculado pela combinação desses subíndices.
