In this paper, we propose a composite multiple-mode orthogonal frequency division
multiplexing with index modulation (C-MM-OFDM-IM) scheme to increase the spectral …

Generalized quadrature spatial modulation (GQSM) seamlessly amalgamates the
generalized spatial modulation (GSM), quadrature spatial modulation (QSM) and vertical …

In this letter, we employ quadrature spatial modulation (QSM) in both transmitter and
receiver with the assistance of an intelligent reflecting surface (IRS), which we refer to as IRS …

In this paper, we study energy‐efficient power allocation (PA) to secure the confidential
information of massive multiple‐input multiple‐output (MIMO) systems in the presence of an …

Abstract 5G and future generation networks require physical layer security (PLS) to reinforce
the security at the higher communication layers. A novel technique of securely transmitting …

The massive multiple input multiple output (mMIMO) provides reliable base station (BS) for
the mobile users (MUs) with CSI (channel state information) and jointly offers spectral …

Abstract Generalized Spatial Modulation (GSM) is a recent Multiple-Input Multiple-Output
(MIMO) scheme, which achieves high spectral and energy efficiencies. Specifically, soft …

In this paper, the performance of precoding‐aided differential spatial modulation (PDSM)
systems with optimal transmit antenna subset (TAS) selection is examined analytically. The …

In this paper, a new MIMO scheme termed as precoded Spatially Modulated Non-orthogonal
Space Time Block Code (precoded SM-NSTBC) is proposed. The primary concept of …

Multiple input multiple output (MIMO) based non‐orthogonal multiple access (NOMA) has
been an evolving technique for 5G and beyond 5G wireless networks in the last decade. The …
