Abstract
A radio equipment separates a signal of a specific terminal from signals from adaptive array antennas # to # , based on a reception weight vector calculated by a reception weight vector calculator . Reception coefficient vector calculator provides an impulse response of a signal propagation path of the specific terminal. A transmission coefficient vector estimator predicts a propagation path at the time of transmission, from the result of estimation by the reception coefficient vector calculator . The transmission weight vector calculator controls, based on the result of prediction by the transmission coefficient vector estimator , the antenna directivity at the time of transmission. Thus, degradation of error rate of the down link generated by the time difference between up/down links can be suppressed.
