| Popis: | 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 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. |
