Single-Input-Multiple-Output Systems Modulation Using Quadrature Media Schemes

The restriction of single-input multiple-output (SIMO) schemes is improved by media-based SIMO (MBM- SIMO), which also improves error performance by means of reducing the quantity of antennas needed to transmit a sizable quantity of data. As a way to improve the functionality of the MBM- SIMO, we use the spatial constellation's quadrature dimension in this study by decomposing the symbol of amplitude/phase modulation (APM), analogous to quadrature spatial modulation (QSM) and to accomplish a higher data rate. The Monte Carlo simulation (MCS) results are developed and used to establish the system's theoretical average error probability of the proposed scheme applying a lower bound method. The obtained MCS results show a significantly better improvement of 3dB at 10b/s/Hz with
${{m}_{rf}} = 2$
and 6.5dB at 12b/s/Hz with
${{m}_{rf}} = 4$
over the standard MBM- SIMO system.
