Abstract

　ＯＦＤＭＡ方式によって無線通信を行なう無線通信装置であって、複数の受信信号ベクトルをサンプル値として用いることにより相関行列及び相関ベクトルを算出し、算出された相関行列及び相関ベクトルに基づいてＳＭＩウェイトを導出するＳＭＩウェイト導出部（１４）と、ＳＭＩウェイト導出部（１４）によって導出されたＳＭＩウェイトを受信信号ベクトルに乗算するウェイト乗算部（１５）とを備え、ＳＭＩウェイト導出部（１４）は、ＯＦＤＭＡ方式におけるユーザ割り当て領域に含まれる複数のサブキャリアの各々の受信信号ベクトルをサンプル値として用いることにより、ユーザ割り当て領域用のＳＭＩウェイトを導出する。
