Abstract	We have proposed a hybrid single-carrier (SC) and multi-carrier (MC) system for next-generation mobile communication systems. By appropriately selecting SC or MC signal, both high data rate and wide coverage system are attained in the hybrid system. In this paper, we discuss multi-antenna technology for the hybrid system. When space division multiplexing (SDM) is applied to the hybrid system, the maximum throughput is increased by SDM; however, the uplink coverage is narrowed under the condition of constant total output power. To widen the coverage, we propose adaptive multi-antenna transmission scheme that optimally selects SDM or joint detection of frequency-domain equalization (FDE) with antenna diversity. A computer simulation is carried out to estimate the uplink throughput performance of the proposed hybrid system. The simulation results show that wider coverage is attained by 41 % than SDM when the uplink throughput at a cell edge is 0.5 bit/s/Hz, while keeping the same maximum throughput as that of SDM.
