Abstract

"MéTODO E APARELHO DE CODIFICAçãO/DECODIFICAçãO UTILIZADO EM UM SISTEMA DE COMUNICAçãO MóVEL CDMA". Um método de codificação em um sistema de comunicação móvel, para receber 4 bits de informação de entrada, codificar os 4 bits de informação de entrada com códigos Walsh diferentes de comprimento 16 e dar saída a um fluxo de símbolos codificados tendo 24 símbolos codificados usando um fluxo de símbolos codificados tendo 16 símbolos codificados obtidos pela verificação de XOR dos bits de informação de entrada codificados por um operador XOR. O método de codificação compreende repetir o fluxo de símbolos codificados tendo 16 símbolos codificados uma vez e, desta forma, dar saída a um fluxo de símbolos codificados tendo 32 símbolos codificados e perfurar os 0<0>, 1<0>, 2<0>, 3<0>, 4<0>, 5<0>, 6<0> e 16<0> símbolos dos 32 símbolos codificados e dar saída no fluxo de símbolos codificados tendo 24 símbolos codificados.
