摘要：Signal component converging section 105 delays received signal components spread on a time axis to combine signal components based on an output of propagation path estimating section 104, maximum value detecting section 106 detects a sample timing of a signal component with the maximum power among signal components combined in signal component converging section 105, and tap coefficient estimating section 107 estimates a tap coefficient that minimizes a mean square of a difference between a replica signal and a received signal while assigning a tap coefficient of a fixed value (for example, 1) to a sampling timing providing the maximum power, and outputs the estimated tap coefficient to FFF in plural array combining section 102 and a replica generating section in Viterbi equalizer 108.
