This paper proposes list Viterbi equalizers (LVEs) that use two kinds of metric criteria for wide-spread time-dispersive channels to achieve a good trade-off between complexity and bit error rate (BER) performance. For Viterbi equalization employing a state-reduction algorithm, the modified metric criterion proposed by Ungerboeck is not always equivalent to the squared Euclidean distance metric criterion. This paper proposes the following two schemes for the LVE: (1) to combine two kinds of metric criteria like combining diversity; (2) to select the metric criterion like selection diversity according to the channel impulse response. Finally, computer simulation shows that the proposed schemes improve BER performance on wide-spread frequency selective fading channels, even if the proposed schemes have smaller complexity than the conventional one.
