摘要：
In this paper, single-carrier block spread CDMA for multiple-input-multiple-output (MIMO) systems is proposed. With block spreading and despreading, multiple-user interference free(MUI-free) transmission with reduced processing complexity is achieved. Layered space-time transmission (LST) is employed to enhance the data rate of the proposed system. The proposed system is studied extensively under different channel conditions and its performance is compared against conventional single-carrier and multicarrier CDMA systems.
