This paper describes an inexpensive as well as efficient adaptive antenna array processor for a code division multiple access (CDMA) wireless communications system, e.g., 3rd generation (3G) CDMA2000 or W-CDMA system. Separate channel estimation is not required in this paper while it has been used for a CDMA system with a conventional adaptive antenna array. In addition, the phase distortions due to the different radio frequency (RF) mixers can be compensated automatically in this paper. Thus, separate phase calibration is not necessary for an adaptive antenna array processor if the reverse link demodulation is concerned. Furthermore, bit error rate (BER) performance of a CDMA system with the adaptive algorithm in this paper can be smaller than that with a conventional algorithm under fading and additive white Gaussian noise (AWGN) environments
