Abstract
"MéTODO PARA CODIFICAR E DECODIFICAR UMA SEQUêNCIA DE BITS PARA A TRANSMISSãO ATRAVéS DO CANAL DE TRANSMISSãO, APARELHO DE TRANSMISSãO E DE RECEPçãO PARA CODIFICAR E DECODIFICAR UMA SEQUêNCIA DE BITS, E, SISTEMA PARA COMUNICAçãO SEM FIO". Método e aparelho correspondente para codificar uma seq³ência de bits para transmissão como símbolos, algumas das posições de bit dos símbolos possuindo uma taxa de erro de bit mais alta do que as outras posições de bit. O método inclui os passos de: prover (31, 32, 41, 42) uma pluralidade de seq³ências de bits usando um codificador convolucional (31, 41), em resposta á uma seq³ência de bits de entrada, cada seq³ência de bits sendo definida por um polinómio gerador predeterminado possuindo um nível predeterminado de sensibilidade ao mapeamento; mapear (33, 44) os bits de cada seq³ência de bits para as posições de símbolo baseadas no nível de sensibilidade do polinómio gerador que define a seq³ência de bits. Com a intercalação, o mapeamento dos bits de cada seq³ência de bits para as posições de símbolo (33, 44) pode preceder o passo de intercalação (34) de símbolo, ou pode seguir o passo de intercalação (43) de bit.
