Abstract :
The uplink capacity of cellular systems, where the co-channel interference (CCI) limits the system capacity more than thermal noise, is investigated in this paper. We evaluate the overall system capacity under slow fading when space-time block codes (STBC) are employed. A power control technique suited for STBC is proposed to improve the bit error rate (BER) performance on the target link and the system capacity. Handover is also considered to provide further improvement on the system capacity
