RECEIVING DEVICE, RADIO BASE STATION, AND RECEIVING METHOD

摘要

A weight calculating section (140) of a receiving device (10) comprises an antenna weight processing section (140A) and an equalization weight processing section (140B). The antenna weight processing section (140A) sets the initial values of antenna weights (w*1 to w*R) to an antenna weighting section (115). The equalization weight processing section (140B) calculates equalization weights (c*0 to c*M) by using an optimization algorithm in the state in which the initial values are held in the antenna weighting section (115). The antenna weight processing section (140A) calculates the antenna weights (w*1 to w*R) by using the optimization algorithm in the state in which the calculated equalization weights (c*0 to c*M) are held in a feed-forward section (120A).
