CORTEZ, Joaquín et al. Detection scheme for linear dispersion space-time block codes using modified SQRD decomposition. Nova scientia [online]. 2017, vol.9, n.18, pp.239-256. ISSN 2007-0705.  https://doi.org/10.21640/ns.v9i18.821.

In this work, a novel architecture for detection of Hybrid MIMO Systems over Rayleigh fading channels is presented. The Hybrid MIMO scheme consists of one Alamouti space-time block code unit, plus n s antennas operating as layers of V-BLAST in the transmitter. The proposed receiver is based on the algorithm Sorted QR decomposition (SQRD) presented in (Wubben et al., 2001). This proposal reduces significantly the complexity while maintaining the advantages of the SQRD scheme, obtaining a considerable gain in performance in terms of bit error rate (BER) at the expense of decreasing data rate.
