Abstract

"INTERCALAçãO DE BLOCO PARA TURBO CODIFICAçãO".Um intercalador recebe quadros de dados de entrada do tamanhoN. o intercalador indexa os elementos do quadro com um arranjode índice de N~ 1~ x N~ 2~. O intercalador então efetivamentereorganiza (permuta) os dados pela permuta das linhas do arranjodo índice. O intercalador utiliza a equação I(j,k)=I(j,(<244>~j~k+<225>~ j~)modP) para permutar as colunas (indexadas por k)de cada linha (indexada por j) . P é pelo menos igual a N~ 2~,<225>~ j~ é uma constante que pode ser diferente para cadalinha, e cada <244>~ j~ é um número primo relativo em relação aoP. Depois da permuta, o intercalador gera os dados em uma ordemdiferente da recebida (por exemplo, recebe seq³encialmente linhapor linha, gera seq³encialmente cada coluna por coluna).
