ABSTRACT:
This invention relates to an equalization apparatus, an equalization method and a receiver using the same. Two equalizers are applied to the equalization apparatus to cover two clusters of a channel. The weights of the two equalizers are calculated by channel gains of the whole channel based on the minimum mean square error criterion. Therefore the interference of the whole channel due to different clusters can be reduced enormously.
