Abstract

The performance of smart antenna in an indoor environment, with the emphasis on improving the system capacity of direct sequence code division multiple access (DS-CDMA) base station is studied. A model for the uplink CDMA is presented which assumes that the base station alone uses an antenna array to transmit and receive signals. In the channel model we assume that the signal bandwidth is much larger than the coherence bandwidth to assure the existence of resolvable paths. The base station uses Differential Phase Shift Keying (DSPK) for modulation and a RAKE receiver. -- Evaluation of different performance measures such as bit error probability and outage probability is performed. A significant improvement in capacity for the 8 sensors smart antenna over the conventional one antenna element is achieved.
