Abstract
The present invention is an encoder and decoder that eliminate all infinitely propagating error sequences for many sets of taps. The encoder includes an input circuit operable to receive an unencoded data signal and an encoding circuit, coupled to the input circuit, operable to generate the encoded data signal using a code that eliminates infinitely propagating error sequences when the encoded data signal is recovered by a decision feedback equalizer data recovery channel. The decoder includes an input circuit operable to receive an encoded data signal and a decoding table, coupled to the input circuit, operable to generate the decoded data signal using a code that eliminates infinitely propagating error sequences when the encoded data signal is recovered by a decision feedback equalizer data recovery channel.
