Abstract

"IMPLEMENTAçãO EFICIENTE DE INTERCALADORES DE TURBO CóDIGO PROPOSTOS PARA ACESSO MúLTIPLO POR DIVISãO DE CóDIGO DE TERCEIRA GERAçãO". A invenção refere-se a métodos e aparelho para intercaladores de Turbo Código para uso com dados de acesso múltiplo por divisão de código de terceira geração (3G CDMA). O aparelho inclui uma memória para receber e temporariamente armazenar os dados, um contador e um relógio acoplado na memória e contador para sincronização. O aparelho também inclui uma tabela contendo endereços que são selecionados pelo contador. Um dispositivo de invalidação acoplado na tabela descarta os endereços se eles são maiores do que um tamanho de quadro. Uma memória intermediária é acoplada na memória e no relógio. A memória é configurada para recuperar dados dos endereços selecionados que não são descartados e enviá-los para a memória intermediária para saída.
