An adaptive Viterbi equalizing method and a related apparatus are disclosed. The apparatus includes a match filter for equalizing a plurality of original symbols of a received signal to generate a plurality of equalized symbols according to a plurality of channel responses, a Viterbi detector for generating a soft-decision value corresponding to a specific original symbol and generating a plurality of hard-decision values corresponding to the original symbols according to the equalized symbols, and an adaptive channel estimation circuit for generating a reproduced symbol through utilizing the channel responses and the hard-decision values and for adjusting one of the channel responses through utilizing the soft-decision value and a difference between the reproduced symbol and the specific original symbol.
