Abstract

"DECODIFICADOR EM TRELIçAS E EQUALIZADOR DE REALIMENTAçãO DE DECISãO COMBINADOS". Trata-se de um equalizador adaptativo compreende um decodificador em treliças; um mapeador acoplado à saída do decodificador em treliças, e um equalizador de realimentação de decisão acoplado à saída do mapeador. Cada uma das derivações recebe como entrada pelo mapeador a saída de um dos estágios diferentes do decodificador em treliças.
