As a low-cost and low-power-consumption passive reflector, intelligent reflecting surface
(IRS) can make a significant rate improvement by building a programmable wireless …

This paper investigates intelligent reflecting surface based backscatter communication (IRS-
BackCom), in order to realize computational task offloading of energy-constrained mobile …

Cognitive ambient backscatter communication is a novel spectrum sharing paradigm, in
which the backscatter system shares not only the same spectrum, but also the same radio …

This letter first proposes to resist undesired signal such as interference or jamming signal
using intelligent reflecting surface (IRS)-based backscatter communication system. When …

Backscatter communication (BackCom) is considered as one of important techniques to
extend the lifetime of Internet of Things (IoT). How to achieve resource allocation (RA) is a …

Intelligent reflecting surface (IRS) is a newly emerged technology that can increase the
energy and spectral efficiency of wireless communication systems. This paper considers an …

Tag signal detection is one of the key tasks in ambient backscatter communication (AmBC)
systems. However, obtaining perfect channel state information (CSI) is challenging and …

This paper studies the transmit strategy for a secondary link or the so-called cognitive radio
(CR) link under opportunistic spectrum sharing with an existing primary radio (PR) link. It is …

We focus on an intelligent reflecting surface (IRS)-assisted multiple-input single-output
(MISO) system where the IRS sustains its operations by harvesting energy from the access …

The cloud radio access network (C-RAN) concept, in which densely deployed access points
(APs) are empowered by cloud computing to cooperatively support mobile users (MUs), to …
