In this paper, we explore the impacts of utilizing intelligent reflecting surfaces (IRS) in a power-splitting based simultaneous wireless information and power transfer (PS-SWIPT) system and compare its performance with the traditional decode and forward relaying system. To analyze a more practical system, it is also assumed that the receiving nodes are subject to decoding cost, and they are on...

In this work, SiO2 –ZrO2 mixed oxides was prepared by the polymeric sol–gel route. The characterization of pore structure, which determines the permeation process of membrane, is of great importance. So far, most investigations have focused on such pore structure as specific surface area and pore size distribution, but the surface fractal, the important parameter reflecting the roughness of por...

Industry 5.0 envisions close cooperation between humans and machines requiring ultra-reliable low-latency communications (URLLC). The intelligent reflecting surface (IRS) has the potential to play a crucial role in realizing wireless URLLC for 5.0. IRS is forecast be key enabler of 6G communication networks as it can significantly improve network performance by creating controllable radio envir...

<span>Terahertz (THz)-band communications can be considered as the new frontline for future-generation wireless communication systems it has a wider bandwidth in comparison to microwave and mmwave communications. It also promises integrate wide range of diverse applications. Because high path loss narrow spreading THz waves, transmission is extremely sensitive signal coverage critical pro...

This work proposes linear time strategies to optimally configure the phase shifts for reflective elements of an intelligent reflecting surface (IRS). Specifically, we show that binary beamforming can be solved in maximize received signal-to-noise ratio (SNR). For general K-ary beamforming, develop a approximation algorithm guarantees performance within constant fraction (1+\cos(\pi/K))/2 global...

A simultaneously transmitting and reflecting surface (STARS) aided terahertz (THz) communication system is proposed. novel power consumption model proposed that depends on the type resolution of STARS elements. The spectral efficiency (SE) energy (EE) are maximized in both narrowband wideband THz systems by jointly optimizing hybrid beamforming at base station (BS) passive STARS. 1) For systems...
