Abstract :
This paper discusses performance of a list Viterbi equalizer (LVE) employing a metric-criteria combining (MCC) scheme, which weighted-combines the squared Euclidean metric and the modified metric proposed by Ungerboeck (1974). First, it evaluates hardware implementation aspects of LVEs. Next, it discusses performance aspects of the metric criteria. Finally, it is confirmed by computer simulation that MCC-LVEs can cope with the path diversity gain at relatively small hardware complexity in the presence of wide spread ISI and MCC-LVEs with diversity reception improve the packet error rate (PER) performance even if there exist large number of effective fading paths
