Abstract

"PROCESSAMENTO DE CAMADA FìSICA PARA UM SISTEMA DE COMUNICAçãO SEM FIO UTILIZANDO ACESSO MúLTIPLO POR DIVISãO DE CóDIGOS". A presente invenção inclui várias realizações para uso em processamento de camadas físicas. Uma realização determina o mapeamento de endereços de bits no separador de canais físicos a partir do endereço de bits no primeiro separador de entrelaçamento. Os endereços do separador de canais físicos são determinados de forma correspondente aos endereços dos bits após o emparelhamento de velocidades, a codificação dos bits, segundo entrelaçamento e mapeamento de canais físicos. Os bits são lidos diretamente do primeiro separador de entrelaçamento e escritos para o separador de canais físicos, utilizando os endereços de separador de canais físicos determinados. Outra realização determina o mapeamento de endereços de bits no primeiro separador de entrelaçamento a partir do endereço de bits no separador de canais físicos. São determinados os primeiros endereços de separadores de entrelaçamento, correspondentes a endereços dos bits após a reversão do emparelhamento de velocidades, reversão da codificação de bits, reversão do segundo entrelaçamento e reversão do mapeamento de canais físicos. Os bits são lidos diretamente dos endereços de primeiros separadores de entrelaçamento determinados e escritos para os endereços de separadores de canais físicos.
