Abstract :
The uplink and downlink capacity for a CDMA system with an adaptive antenna array is analyzed when an angle estimation error is present. For the modulation and spreading schemes, dual channel BPSK with complex spreading in the uplink and QPSK with quadriphase spreading in the downlink are employed as in the asynchronous W-CDMA system. Also in this paper, an attempt for comparing the capacity on different channel environments has been made
