Abstract

"MéTODO E APARELHO PARA DESENTRELAçAR UM FLUXO DE DADOS ENTRELAçADO EM UM SISTEMA DE COMUNICAçãO". Um aparelho e método para ler símbolos gravados por desentrelaçamento para decodificar um pacote de codificador gravado em um receptor para um sistema de comunicação móvel que suporta codificação turbo e entrelaçamento, tal que o pacote de codificador codificado por turbo/entrelaçado tem um valor de deslocamento de bit m, um valor de limite superior J e um resto R, e um fluxo de símbolos do pacote de codificador é gravado em ordem de coluna para linha. O aparelho e método efetuam as operações de gerar um endereço provisório por ordem inversa de bits (BRO) supondo que o resto R é 0 para os símbolos recebidos; calcular um fator de compensação de endereço para compensar o endereço provisório em consideração de uma coluna formada com o resto; e gerar um endereço de leitura ao acrescentar o endereço provisório e o fator de compensação de endereço para um símbolo necessário para a decodificação, e ler um símbolo gravado no endereço de leitura gerado.
