A base station device comprises antenna elements for each branch so arranged at predetermined locations in a horizontal plane unique to respective systems as to have a mutually vertical positional relationship, a signal processing means for generating a weight unique to each system by effecting an adaptive array antenna processing of the signals received by the antenna elements of each branch and for generating a synthetic signal produced by combining synthetic signals generated by multiplying the signals received by the antennas of each system by the weight, and diversity synthesizing means for generating a reception signal by effecting diversity synthesization using the synthetic signal of each branch. Therefore, the influence of the fading and interference is suppressed while maintaining the good communication quality of a mobile station device, and thereby a reception signal of good characteristics can be produced.
