This article addresses the practical aspects that may affect the performance of down-link non-
orthogonal multiple access (NOMA) systems. The system performance of two down-link …

In this paper, we accurately model the impact of aggregate hardware impairments (HWIs) in
communication systems as improper Gaussian signals (IGS), which can describe the …

In this paper, we analyze the performance degradation of a multi-hop decode-and-forward
full-duplex relaying system caused by the residual self-interference (RSI) and hardware …

Error probability study of hardware impaired (HWI) systems highly depends on the adopted
model. Considering the distinct improper Gaussian features of HWI systems, captured by …

In this paper, we study the advantages of improper Gaussian signaling (IGS) with the
existence of hardware impairments (HWI) and imperfect successive interference …

Future wireless communication systems, including fifth-generation (5G) networks and the
Internet of Things (IoT), require a massive number of inexpensive transceivers. These …

Multiple-input-multiple-output (MIMO) dual-func-tional radar communication (DFRC)
provides a solution to the severe spectrum scarcity challenge. MIMO systems may be prone …

Hardware distortions (HWDs) render drastic effects on the performance of communication
systems. They are recently proven to bear asymmetric signatures; and hence can be …

Systems based on orthogonal frequency division multiplexing (OFDM) are subject to
limitations caused by the radio front end. These deficiencies are the result of imbalances …

Quadrature spatial modulation (QSM) isa recently proposed multiple-input multiple-output
(MIMO) wireless transmission paradigm that has garnered considerable research interest …
