A reception quality measuring circuit (107) measures the reception quality of received data outputted from an adder (103). When the reception quality measured by the reception quality measuring circuit (107) is less than a certain threshold value, a transmission antenna weight control circuit (108) outputs, to multipliers (1061-106N), the stored transmission antenna weights, that is, the transmission antenna weights W" stored when the reception quality exceeded the threshold value at the last time, instead of the transmission antenna weights W' outputted by an antenna weight converting circuit (105). |
