Intelligent reflecting surface (IRS) is a promising technology to boost the efficiency of wireless energy transfer (WET) systems. However, for multiuser WET system, simultaneous multi-beam transmission generally required achieve maximum performance, which may not be implemented by using IRS having only single set coefficients. As result, it remains unknown how exploit approach such performance ...

Recently, intelligent reflecting surface (IRS) has become a research focus for its capability of controlling the radio propagation environments. Compared to conventional terrestrial IRS, aerial IRS (AIRS) exploiting unmanned vehicle (UAV)/high-altitude platform (HAP) can provide better deployment flexibility. To this end, three-dimensional (3D) one-cylinder model is first developed AIRS-assiste...

This paper investigates the passive beamforming and deployment design for an intelligent reflecting surface (IRS) aided full-duplex (FD) wireless system, where FD access point (AP) communicates with uplink (UL) user a downlink (DL) simultaneously over same time-frequency dimension help of IRS. Under this setup, we consider three cases: 1) two distributed IRSs placed near UL DL user, respectivel...

This letter studies the performance of a single-input single-output (SISO) system enhanced by assistance an intelligent reflecting surface (IRS), which is equipped with finite number elements under Rayleigh fading channels. From instantaneous channel capacity, we compute closed-form expression coverage probability as function statistical information only. A scaling law and phase shifts further ...

Intelligent reflecting surface (IRS) is envisioned as a key technology for the next-generation wireless communication systems that enhances coverage and performance by reconfiguring propagation environment. In this letter, of an IRS-aided wireless-powered internet-of-things (IoT) network over Rayleigh fading channels investigated consists power station, IRS, access point, IoT devices. particula...

The operation of an intelligent reflecting surface (IRS) under predictable receiver mobility is investigated. We develop a continuous time system model for multipath channels and discuss the optimal IRS configuration with respect to received power, Doppler spread, delay spread. It shown that power can be maximized without adding spread system. In numerical case study, we show having size just t...
