ABSTRACT:
Reception quality measuring circuit (107) measures the reception quality of received data delivered from adder (103). When the reception quality measured by reception quality measuring circuit (107) is less than a certain threshold value, transmission antenna weight control circuit (108) applies multipliers (1061–196N) with stored transmission antenna weights, that is, transmission antenna weight W″ stored therein when the reception quality exceeded the threshold value at the last time, instead of transmission antenna weights W′ generated by antenna weight converting circuit (105).
