Abstract(in English)	This paper proposes an efficient adaptive array antennas for base station in CDMA system. The proposed scheme employs a common correlation matrix by which weights of adaptive arrays are determined for multiple users and multiple taps of RAKE receiver. Since the base station hsa only one calculator for correlation matrix, the proposed scheme make it possible to decrease the computational burden for adaptive array drastically. Numerical results show that the proposed scheme has less computational burden than the conventional scheme with LMS algorithm. It is also shown that the proposed scheme has good bit error rate performance under multiple users.
