Sequence estimation method and sequence estimator |
摘要 |
In a sequence estimation method and a sequence estimator of the present invention, a metric is calculated using a received signal and its estimated value, also another metric is calculated using a filtering result via a matching filter, one of these metrics is selected based on a characteristic of the channel or these metrics are combined, when a transmitted signal sequence transmitted from a transmission side is estimated based on a characteristic of a received signal and a channel using a list output Viterbi algorithm for deciding one or a plurality of survivors for each state of the Viterbi algorithm including one or more states. The operation speed and the characteristic of a channel can be improved using the smallest circuit scale even if the characteristic of a channel has a long delay time, in a sequence estimation method and a sequence estimator.
