Abstract:
1. An equalizer comprising: a replica generation means for generating a replica of a multipath component by applying an adaptive filter to a received signal which has received multipath interference; a removal means for generating a multipath-component removed signal which is the received signal from which the multipath component has been removed by subtracting the replica generated by the replica generation means 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 generated by the replica generation means is the replica of the multipath component included in the received signal or not based on the correlation value calculated by the correlation value calculation means and the power value calculated by the power value calculation means; and a selection means for outputting the multipath-component removed signal generated by the removal means when it is determined that the replica generated by the replica generation means is the replica of the multipath component included in the received signal by the determination means, and outputting the received signal when it is determined that the replica generated by the replica generation means is not the replica of the multipath component included in the received signal by the determination means.
