- W2083005526 abstract "In this paper, we propose a limited feedback precoded stacked space-time architecture where the components are taken from orthogonal designs. This stacked architecture allows to achieve high spectral efficiency. Precoding the stacked matrix is used to separate and decode efficiently the different components at a reasonable complexity and to improve array gain. We consider at the receiver a V-BLAST signal processing which is based on a successive component interference suppression. We propose a criterion for selecting the precoding matrix among Grassmannian codebook matrices that maximizes the minimum signal to interference and noise ratio over all components of the stacked design. Two stacked architectures are considered for simulations. We show that these two architectures, with limited feedback precoding, outperform the precoded spatial multiplexing systems for the same number of transmit and receive antennas, the same spectral efficiency and the same number of bits on the feedback link." @default.
