In this paper, we investigate the performance of a multi-user downlink (DL) multiple-input multiple-output (MIMO) aided code division multiple access (CDMA) using polarization multiplexing (PM). We consider triply-Polarized antennas to establish PM that possess the advantage of replacing the uni-Polarized antennas which impose space constraints. In order to accommodate more user populations, we consider...
This paper evaluates the performance of dual-polarized double space time transmit diversity (DSTTD) aided multiple input multiple output (MIMO) interleave division multiple access (IDMA) scheme over correlated frequency-selective channels for downlink (DL) communication. DSSTD system employs two space-time block code (STBC) units at the transmitter side. In our considered work, we employ two dual-polarized...
In this contribution, we investigate the performance of dual-polarized multi input multi output (MIMO) multi-carrier interleave division multiple access system (MC-IDMA) over correlated frequency selective channels in the presence of channel state estimation error. In the code division multiple access (CDMA), orthogonal spreading sequence is used as user specific where as in IDMA, user specific interleaving...
