| Abstract(in English) | This report presents single carrier multiuser multiple input multiple output (MU-MIMO) downlink transmission schemes under frequency selective channels based on extension of narrow band MU-MIMO techniques. First, broadband version of channel inversion method adopting time-domain processing is considered, then it is arranged to broadband vector perturbation (VP) method based on QRD-M algorithm. Simultaneously, the possibility of broadband VP using channel inversion with regularization factor has been considered. In those methods, transmitter is equipped with spatio-temporal filters adopting tapped delay line (TDL) structure instead of simple weight. Through computer simulations, the effectiveness and problems of those approaches are shown. |
