Abstract: A decision feed back equalizer is proposed, in which two feed back routins are provided for one symbol-preceding decided data. The signal space is separated into decidable areas and uncertainty areas in the present invention. Each of decidable areas is an area where a distance between any point in the decidable area and the signal point is small. Each uncertainty areas is an area where a distance between any point in the uncertainty area and the signal point is large. In a case where the one symbol-preceding equalized signal exists in a decidable area, since the one symbol-preceding decided data is presumed to be correct, the decided data is fed back.
