Abstract:
An equalizer includes: a replica generation means for generating a replica of a multipath component by applying an adaptive filter to a received signal; a removal means for generating a multipath-component removed signal from which the multipath component has been removed by subtracting the replica from the received signal; a correlation value calculation means for calculating a correlation value between the received signal and the replica; a power value calculation means for calculating a power value of the replica; a determination means for determining whether the replica is the replica of the multipath component based on the correlation value and the power value; and a selection means for outputting the multipath-component removed signal when it is determined that the replica is the replica of the multipath component, and outputting the received signal when it is determined that the replica is not the replica of the multipath component.
