While intelligent reflecting surface (IRS) assisted wireless communication has emerged as an important research paradigm, channel state information (CSI) acquisition remains a critical challenge to design the IRS phase-shifts and yield promised coherent beamforming gains. In this letter, we propose IRS-assisted opportunistic (OBF) scheme under proportional fair scheduling, which does not requir...

In this work, we propose a novel hybrid communication network that utilizes both Full-Duplex (FD) Decode-and-Forward (DF) relay and an Intelligent Reflecting Surface (IRS) to support data transmission over wireless channels. We design the reflecting coefficients at IRS maximize minimum achievable rate of two hops for proposed network. To end, utilize change-of-variables with Semi-Definite Relax...

Optical intelligent reflecting surfaces (OIRS) have the potential to enhance capacity of next generation optical wireless communication systems by re-configuring propagation environment waves. In this work, a submerged OIRS and planar mirror surface (PMS) are used build up non-line sight (NLOS) underwater (UWOC) system. An NLOS UWOC setup, which makes use total internal reflection (TIR) phenome...

Intelligent reflecting surface (IRS) is a promising technology for enhancing wireless communication systems. It adaptively configures massive passive elements to control channel in desirable way. Due hardware characteristics and deploying environments, an IRS may be subject element blockages failures, hence developing diagnostic techniques of great significance system monitoring maintenance. In...

In this paper, secure transmission in a simultaneous wireless information and power transfer technology-enabled heterogeneous network with the aid of multiple IRSs is investigated. As potential technology for 6G, intelligent reflecting surface (IRS) brings more spatial degrees freedom to enhance physical layer security. Our goal maximize secrecy rate by carefully designing transmit beamforming ...

The growing demand for virtual reality (VR) applications requires wireless systems to provide a high transmission rate support 360-degree video streaming multiple users simultaneously. In this paper, we propose an intelligent reflecting surface (IRS)-aided rate-splitting (RS) VR system. the proposed system, RS facilitates exploitation of shared interests in streaming, and IRS creates additional...
