Passive tags must harvest sufficient energy to operate. However, ensuring the tag's energy
needs and simultaneously suppressing the interference in ambient backscatter systems is …

Bistatic backscatter communication (BackCom) allows passive tags to transmit over
extended ranges, but at the cost of having carrier emitters either transmitting at high powers …

We introduce a novel system setup where a backscatter device operates in the presence of
an intelligent reflecting surface (IRS). In particular, we study the bistatic backscatter …

In a backscatter communication system, the backscatter device (BD) transmits its messages
to the backscatter receiver (BR) by reflecting the incident signal from an external radio …

Intelligent reflecting surface (IRS) is a 2D surface made up of metasurface, on which passive
elements such as varactor diodes interact with incoming electromagnetic waves and …

Ambient backscatter devices (tags and readers) use existing radio frequency (RF) signals to
transmit data. Most prior works consider single-antenna tags, but this paper investigates the …

Passive technologies like ambient backscatter communication (AmBC) and intelligent
reflecting surface (IRS) hold enormous potential for ubiquitous connectivity of Internet of …

Intelligent reflecting surface (IRS) is a promising technology to improve the performance of
backscatter communication systems by smartly reconfiguring the multi-reflection channel. To …

The performance of cooperative ambient backscatter communications (CABC) can be
enhanced by employing reconfigurable intelligent surface (RIS) to assist backscatter …

In this paper, we investigate and analyze a hybrid ambient backscatter (AmBack) scheme
with harvest-then-transmit protocols. In this scheme, the whole transmission is divided into …
