摘要

本文讨论了采用度量标准组合(MCC)方案的列表Viterbi均衡器(LVE)的性能，该方案加权组合了平方欧几里得度量和Ungerboeck(1974)提出的修正度量。首先，它评估lve的硬件实现方面。接下来，讨论度量标准的性能方面。最后，通过计算机仿真验证了MCC-LVEs可以在广泛ISI存在的情况下以相对较小的硬件复杂度应对路径分集增益，即使存在大量有效衰落路径，具有分集接收的MCC-LVEs也能提高包错误率(PER)性能。

Performance of list Viterbi equalizers with metric-criteria combining

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.
