ABSTRACT:
A reception weight calculation section203calculates reception weights W1and W2every antenna using an optimal directional control method in order to improve interference cancellation effect, an arrival direction estimation section204estimates a direction of arrive of a received signal for each antenna to calculate steering vectors S1and S2for each antenna, and a replica weight calculation section211calculates replica weights Wr1and Wr2using the reception weights W1, W2and steering vectors S1, S2.
