摘要：

The application of adaptive array antennas in wireless base stations in cellular mobile communication systems is studied to improve frequency utilization. Since the propagation path information differs in the uplink and the downlink in Frequency Division Duplex (FDD) where the carrier frequencies in the downlink and uplink differ, the method for generating the antenna weights for the downlink is an important topic of study. In this paper, we propose a method that measures the location of the mobile station via the uplink (direction and distance from the base station) and controls the antenna weights of the downlink based on that information. Then we clearly show the improvement in the receive CINR performance in the mobile station when the proposed method was applied to a DS-CDMA cellular system. (c) 2005 Wiley Periodicals, Inc.
