Abstract

''TRANSMISSOR PROCESSO E SISTEMA DE TRANSMISSãO PARA TRANSMITIR SINAIS CODIFICADOS ATRAVéS DE UMA CANAL''. Um transmissor (100) recebe informações para transmissão para um receptor (200) através de um canal de comunicação (101). Um circuito de código de teste de redundância cíclica (CRC) (106) codifica as informações com o código CRC para fins de detecção de erro. As informações CRC codificas são fornecidas a um comutador de código (108). O comutador de código (108) fornece as informações CRC codificadas que a um primeiro circuito de código (110) quer a um segundo circuito de código (112) para codificação de erro antecipada (FEC). O primeiro circuito de código (11) pode, por exemplo, codificar as informações utilizando um Código FEC 1, tal como codificação convolucional, e o segundo circuito de código (112) pode codificar as informações utilizando um Código FEC 2, tal como codificação de repetição. O comutador de código (108 selecionar quer o primeiro quer o segundo circuito de código (110 ou 112) baseado sobre características detectadas do canal (101). As caracterísiticas do canal (101). As características do canal podem ser obtidas de um circuito de estimação de canal (114), podem ser obtidas de um sinal de realimentação de erro I~ 3~ do receptor (200) ou podem ser obtidas de uma combinação de ambos. Após o comutador de código (108) selecionar o primeiro ou segundo circuito de código (110 ou 112), as informações são apropriadamente codificadas para produzir um sinal codificado que é transmitido através do canal (101) por um circuito de transmissão (116).
