Sequence estimation method and sequence estimator

摘要

In a sequence estimation method and a sequence estimation of the present invention, a metric is calculated using a received signal and a channel using a list output Viterbi algorithm to decide one or a plurality of survivors for each state of a Viterbi algorithm including one or more states, the method comprising:
