A reception weight calculation section 203 calculates reception weights W1 and W2 every antenna using an optimal directional control method in order to improve interference cancellation effect, an arrival direction estimation section 204 estimates a direction of arrive of a received signal for each antenna to calculate steering vectors S1 and S2 for each antenna, and a replica weight calculation section 211 calculates replica weights Wr1 and Wr2 using the reception weights W1, W2 and steering vectors S1, S2.
