    Antenna diversity is a powerful technique to mitigate the impact of multipath fading. In a conventional centralized antenna network (CAN), diversity antennas are co-located at base station and hence, the impacts of the propagation path loss and the shadowing loss cannot be mitigated. Distributed antenna network (DAN) is an effective way to mitigate all of the above impacts. The choice of the multi-access technique is a very important issue. In this paper, we consider broadband DS-CDMA with joint minimum mean square error based frequency domain-equalization (MMSE-FDE)/antenna diversity as the multi-access technique for DAN and investigate the link capacity and required transmit power to compare with CAN. It is shown by the computer simulation that DS-CDMA DAN can reduce the required transmit power for the given bit error rate (BER) and can obtain larger uplink cellular capacity than DS-CDMA CAN.
