Abstract

"EQUALIZADOR DE REALIMENTAçãO DE DECISãO PARA TV DIGITAL E MéTODO DO MESMO". O equalizador de realimentação de decisão convencional tem uma desvantagem em que não pode escolher corretamente os símbolos porque um cortador simples é utilizado como detector de símbolos. Um equalizador de realimentação de decisão como um detector de símbolos utiliza um decodificador de Modulação codificada em treliças (TCM) cuja profundidade de localização é 1 (TBD =1), para desse modo escolher corretamente os símbolos sem retardo de decodificação.
