RECEPTION DEVICE, RADIO BASE STATION, AND RECEPTION METHOD

摘要

A reception device weights a reception signal by using antenna weights (w*1 to w*R). A weight control unit (140A) includes: an antenna weight update unit (145A) which updates an antenna weight; a temporary antenna weight calculation unit (142A) which calculates a temporary antenna weight (w'n) which is an antenna weight based on the optimization algorithm; an acquisition unit (143A) which acquires the previous antenna weight (wn-1); and an antenna weight calculation unit (144A) which calculates the current antenna weight wn based on a change tendency from the previous antenna weight to the temporary antenna weight. The antenna weight calculation unit (144A) increases the change amount from the previous antenna weight to the current antenna weight to be greater than the change amount from the previous antenna weight to the temporary antenna weight.
