Abstract

DECODIFICADORES TURBO PARALELOS COM SAìDA MULTIPLEXADA. São providos sistema e método para turbo decodificação de percursos paralelos em um terminal de usuário de comunicações sem fio portátil (UR) . O método aceita um fluxo codificado (306) tendo uma primeira ordem de pacotes de informação, e demultiplexa (304) o fluxo codificado em primeiro fluxo de informação codificada e segundo fluxo de informação codificada (308, 310) . O primeiro fluxo codificado é turbo decodificado (312) gerando um primeiro fluxo decodificado de informação (314) Similarmente, o segundo fluxo codificado é decodificado (316) para gerar um segundo fluxo decodificado de informação (318), assincronamente com relação ao primeiro fluxo decodificado. Então, o primeiro e o segundo fluxos decodificados são combinados (320) em um fluxo combinado (322) tendo uma primeira ordem de pacotes decodificados de informação. O primeiro e o segundo fluxos decodificados são combinados mediante armazenamento em paralelo do primeiro e segundo fluxos decodificados, gerando fluxos decodificados armazenados em paralelo. Então, os fluxos decodificados armazenados em paralelo são multiplexados para criar um fluxo combinado o qual é armazenado em um armazenador de saida.
