This paper investigates the robust beamforming design in a secrecy multiple-input single-output (MISO) network aided by intelligent reflecting surface (IRS) with simultaneous wireless information and power transfer (SWIPT). Specifically, considering that energy receivers (ERs) are potential eavesdroppers (Eves) imperfect channel state (CSI) of direct cascaded channels can be obtained, we invest...

Millimeter wave communication is eminently suitable for high-rate wireless systems, which may be beneficially amalgamated with intelligent reflecting surfaces (IRS), while relying on beam-index modulation. Explicitly, we propose three different architectures based IRSs modulation in millimeter communication. Our schemes are capable of eliminating the detrimental line-of-sight blockage frequenci...

Intelligent reflecting surface (IRS) is an emerging technology to enhance the spectral and energy efficiency of wireless communications cost-effectively. This letter considers a new multi-IRS aided network where cascaded line-of-sight (LoS) link established between base station (BS) remote user by leveraging multi-hop signal reflection selected IRSs. As compared conventional single-/double-hop ...

This letter studies the impact of an intelligent reflecting surface (IRS) on computational performance in a mobile edge computing (MEC) system. Specifically, access point (AP) equipped with server provides MEC services to multiple Internet Thing (IoT) devices that choose offload portion their own tasks AP remaining being locally computed. We deploy IRS enhance system by intelligently adjusting ...

Channel estimation is a practical challenge for intelligent reflecting surface (IRS) aided wireless communication. As the number of IRS elements or IRS-aided users increases, channel training overhead becomes excessively high, which results in long delay and low throughput data transmission. To tackle this challenge, we propose paper new anchor-assisted approach, where two anchor nodes, namely ...
