Abstract

This paper investigates the efficacy of MIMO implementations with adaptive spatial diversity in the uplink of direct spread/code division multiple access (DS/CDMA) cellular systems. Analytical framework to analyze both system capacity and coverage is developed based on the evaluation of outage probability of signal-to-interference ratio (SIR). It is shown that MIMO implementations can significantly improves the system performances; however, transmit diversity and receive diversity shows different system performances contrary to their link level bit error rate (BER) performances.
