IRS-Assisted Ambient Backscatter Communications Utilizing Deep Reinforcement Learning
Xiaolun Jia, Xiangyun Zhou
We consider an ambient backscatter communication (AmBC) system aided by an intelligent reflecting surface (IRS). The optimization of the IRS to assist AmBC is extremely difficult w…
Power Beacon Placement for Maximizing Guaranteed Coverage in Bistatic Backscatter Networks
Xiaolun Jia, Xiangyun Zhou
The bistatic backscatter architecture, with its extended range, enables flexible deployment opportunities for backscatter devices. In this paper, we study the placement of power be…
Intelligent Reflecting Surface-Assisted Bistatic Backscatter Networks: Joint Beamforming and Reflection Design
Xiaolun Jia, Xiangyun Zhou, Dusit Niyato +1
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 or…
Intelligent Reflecting Surface-Aided Backscatter Communications
Xiaolun Jia, Jun Zhao, Xiangyun Zhou +1
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 c…
Performance Characterization of Relaying Using Backscatter Devices
Xiaolun Jia, Xiangyun Zhou
In this paper, we examine the error performance of backscatter communication in the presence of ambient interference, where the backscatter device acts as a relay. Specifically, th…
