We evaluate the uplink capacity of a DS-CDMA cellular system using DPSK modulation with antenna array at base-station. A 2D-RAKE receiver structure with predetection equal gain combining is used for demodulation. We study both the outage and blocking probabilities of the system as a function of the cell loading and the number of array elements. Assuming perfect instantaneous power control and considering the effects of shadowing, multipath fading, path loss, and voice activity, we evaluate the system capacity in terms of the number of users per cell. Simulation results are also presented
