Abstract

"PROCESSOS PARA COMUNICAR INFORMAçãO DE MODO ENTRE UM TRANSMISSOR E UM RECEPTOR EM UM SISTEMA DE COMUNICAçãO, E PARA DECODIFICAR INFORMAçãO, E, SISTEMA DE COMUNICAçãO". Um sistema de comunicação suporta esquemas de codificação de fonte/ codificação de canal múltiplos. Um indicador de modo pode ser transmitido com dados de carga útil para informar o receptor do esquema particular que é empregado atualmente. O indicador de modo pode ser codificado usando uma codificação de canal relativamente fraca para minimizar transmissões de cabeçalho extrínsecas. Para aumentar a probabilidade de decodificar com sucesso o indicador de modo, que tem informação que é altamente importante em decodificar com sucesso os dados de carga útil, vários parâmetros de probabilidade de valor podem ser calculados e combinados para identificar um modo mais provável. Incluído nos parâmetros de probabilidade (suaves) está um parâmetro que pode ser calculado baseado em um modelo do valor provável da informação de modo (por exemplo modelo me Markov).
