An Overview of Signal Processing Techniques for RIS/IRS-aided Wireless Systems
Cunhua Pan, Gui Zhou, Kangda Zhi +8
In the past as well as present wireless communication systems, the wireless propagation environment is regarded as an uncontrollable black box that impairs the received signal qual…
Controlling Smart Propagation Environments: Long-Term versus Short-Term Phase Shift Optimization
Trinh Van Chien, Lam Thanh Tu, Dinh-Hieu Tran +4
Reconfigurable intelligent surfaces (RISs) have recently gained significant interest as an emerging technology for future wireless networks. This paper studies an RIS-assisted prop…
Ambient Backscatter Communications in Mobile Networks: Crowd-Detectable Zero-Energy-Devices
D. -T. Phan-Huy, D. Barthel, P. Ratajczak +3
In this paper, we introduce the new concept of Crowd-Detectable Zero-Energy-Devices. Such devices harvest solar or ambient light energy to power themselves, backscatter ambient wav…
On the Maximum Achievable Sum-rate of the RIS-aided MIMO Broadcast Channel
Nemanja Stefan Perović, Le-Nam Tran, Marco Di Renzo +1
Reconfigurable intelligent surfaces (RISs) represent a new technology that can shape the radio wave propagation and thus offers a great variety of possible performance and implemen…
Spectrum Learning-Aided Reconfigurable Intelligent Surfaces for 'Green' 6G Networks
Bo Yang, Xuelin Cao, Chongwen Huang +6
In the sixth-generation (6G) era, emerging large-scale computing based applications (for example processing enormous amounts of images in real-time in autonomous driving) tend to l…
