Hybrid Transceiver Schemes for Spatial Multiplexing and Diversity in MIMO Systems
AbstractIn this article, we present hybrid multiple-input multiple-output (MIMO) transceiver schemes (HMTS) that combine transmit diversity and spatial multiplexing, thus achieving at the same time the two possible spatial gains offered by MIMO systems. For these transceivers, a modification in the interference nulling-and-cancelling algorithm used in traditional MIMO schemes is proposed. We propose a novel MIMO receiver architecture to cope with the hybrid transmission schemes by jointly performing the tasks of interference cancellation and space-time decoding. Both successive and ordered successive detection strategies are considered in the formulation of the receivers. Our simulation results show satisfactory performance of the HMTS when combined with the proposed receivers, outperforming the standard vertical Bell laboratories layered space-time system in terms of bit/symbol error rate, while providing higher spectral efficiencies than a pure space-time block code system.
