Channel estimation is challenging for the reconfigurable intelligent surface (RIS)-aided
wireless communications. Since the number of coefficients of the cascaded channel among …

In this article, we investigate the resource allocation design for intelligent reflecting surface
(IRS)-assisted full-duplex (FD) cognitive radio systems. In particular, a secondary network …

Increased demand for higher spectrum efficiency, especially in the space-limited chip, base
station, and vehicle environments, has spawned the development of full-duplex …

In-band full-duplex (IBFD) transmission has been identified as a promising solution to
improve spectral efficiency as compared to half-duplex (HD) systems. One of the major …

Wireless backhaul has recently gained a significant amount of interest as a cost-effective
solution in comparison with conventional backhaul technologies with dedicated microwave …

Millimeter-wave (mmWave) massive multiple-input multiple-output (MIMO) systems have
been considered as one of the primary candidates for the fifth generation (5G) and beyond …

This paper considers the optimization of a dual-functional radar and communication
(RadCom) system with the objective is to maximize its sum-rate (SR) and energy-efficiency …

While purely digital phased arrays were once discarded as simultaneous transmit and
receive (STAR) capable platforms, this notion has recently been reconsidered. Previous …

In this paper, we propose a wideband Full Duplex (FD) Multiple-Input Multiple-Output
(MIMO) communication system comprising of an FD MIMO node simultaneously …

This paper addresses the self-interference (SI) cancellation for full-duplex operation in the
presence of imperfect radio-frequency (RF) components. In particular, we develop a new …
