Intelligent Reflecting Surface (IRS)-Aided Covert Communication With Warden’s Statistical CSI

IEEE Wireless Communications Letters, 2021
This work considers covert communications with the aid of an intelligent reflecting surface (IRS). We jointly design the transmit power and IRS’s reflection phase shifts and amplitudes to enhance covert communication performance. To this end, we first derive the total detection error rate at a warden.

Intelligent Reflecting Surface (IRS)-Enhanced Cognitive Radio System

ICC 2020 - 2020 IEEE International Conference on Communications (ICC), 2020
Cognitive radio (CR) is an effective solution to increase the spectral efficiency (SE) of wireless communications by allowing the secondary users (SUs) to share the spectrum with primary users (PUs). On the other hand, intelligent reflecting surface (IRS) is a promising approach to enhance the energy efficiency (EE) of wireless communication systems ...

Intelligent Reflecting Surface (IRS) Allocation Scheduling Method Using Combinatorial Optimization by Quantum Computing

IEEE Transactions on Emerging Topics in Computing, 2022
Intelligent Reflecting Surface (IRS) significantly improves the energy utilization efficiency in 6th generation cellular communication systems. Here, we consider a system with multiple IRS and users, with one user communicating via several IRSs. In such a system, the user to which an IRS is assigned for each unit time must be determined to realize an ...
