In a transmission/reception system, adaptive arrays separate signals from users by multiplying radio wave signals received through array antennas by reception signal weight vectors. A reception signal coefficient vector calculator preliminary calculates a reception signal vector of a U wave and produces a table in a memory. If a cross correlation value of the reception signal vector of the U wave and the reception signal vector of a user newly requesting connection is smaller than a prescribed value, a channel can be allocated to the newly requesting user even if the U wave level per se is high.
