Abstract

MÉTODO E APARELHO PARA CODIFICAR E DECODIFICAR DADOS Um método e aparelho para selecionar tamanhos de intercalador para turbo códigos é aqui provido. Durante a operação o bloco de informação de tamanho K é recebido. Um tamanho de intercalador K' é determinado o qual é relacionado a K", onde K" a partir de um conjunto de tamanhos; em que o conjunto de tamanhos compreende K" = (Alfa)p x f, Pmin (Menor igual) p (Menor igual) pmax ;fmin (Menor igual) f (Menor igual) fmax, em que (Alfa) é um número inteiro e f é um número contínuo entre fmin e fmax, p pega os valores de números inteiros entre pmin e pmax, (Alfa)>1, pmax>pmin, pmin>1. O bloco de informação de tamanho K é preenchido em um bloco de entrada de tamanho K é preenchido em um bloco de entrada de tamanho K' utilizando bits de enchimento, se necessário. A codificação é realizada utilizando o bloco de entrada original e o bloco de entrada intercalado para obter um bloco de palavra-código utilizando um turbo codificador. O bloco de palavra-código é transmitido através do canal.
