Abstract: The conventional decision feedback equalizer has a drawback that can't decide symbols correctly because a simple slicer is used as a symbol detector. A decision feedback equalizer as a symbol detector uses a Trellis Coded Modulation (TCM) decoder whose Trace Back depth is 1 (TBD=1), to thereby decide symbols correctly without decoding delay.

Abstract: A decision feedback equalizing apparatus and a method of decision feedback equalization make a channel property of an inferior receiving signal to mild by using a channel-matched filter and decrease decision errors of symbol detector output signals by using a trellis decoder with decreased complexity, whose trace back depth is 1 (TBD=1).

Abstract: El ecualizador de decisiones realimentadas tiene una desventaja que no puede decidir los simbolos correctamente porque se usa un amplificador simple como un detector de simbolos. Un ecualizador de decisiones realimentadas como un detector de simbolos usa un decodificador de Modulacion Codificada Trellis (TCM) cuya Profundidad de Respaldo de Trazo es 1 por lo tanto decide los simbolos correctamente sin retraso de decodificacion.
