A Tunable Reflection Surface with Independently Variable Phase and Slope
A reconfigurable intelligent surface (RIS) is an essential component in the architecture of the next generation of wireless communication systems.
Transformer Masked Autoencoders for Next-Generation Wireless Communications: Architecture and Opportunities
Next-generation communication networks are expected to exploit recent advances in data science and cutting-edge communications technologies to improve the utilization of the available communications resources.
Enhancing Secret Key Generation in Block Fading Channels using Reconfigurable Intelligent Surfaces
Physical layer security (PLS) is superior to classical cryptography techniques due to its notion of perfect secrecy and independence to an eavesdropper's computational power.
Reconfigurable Intelligent Surfaces Assisted Communication Under Different CSI Assumptions
This work studies the net sum-rate performance of a distributed reconfigurable intelligent surfaces (RISs)-assisted multi-user multiple-input-single-output (MISO) downlink communication system under imperfect instantaneous-channel state information (I-CSI) to implement precoding at the base station (BS) and statistical-CSI (S-CSI) to design the RISs phase-shifts.
Coding for the Gaussian Channel in the Finite Blocklength Regime Using a CNN-Autoencoder
The development of delay-sensitive applications that require ultra high reliability created an additional challenge for wireless networks.
Improving UAV Communication in Cell Free MIMO Using a Reconfigurable Intelligent Surface
In this paper, we propose to solve this challenge using a reconfigurable intelligent surface (RIS) to enhance the UAV communication while preserving the 3GPP- prescribed downwards antenna tilt and potentially improving the DL performance of the GUE.
Alternating Channel Estimation and Prediction for Cell-Free mMIMO with Channel Aging: A Deep Learning Based Scheme
In large scale dynamic wireless networks, the amount of overhead caused by channel estimation (CE) is becoming one of the main performance bottlenecks.
Secure Visible Light Communications via Intelligent Reflecting Surfaces
Further, to enhance the IRS channel gain of the legitimate user while restricting the IRS channel gain of the eavesdropper, we formulate an achievable secrecy rate maximization problem for the proposed IRS-aided PLS technique to find the optimal orientations of mirrors.
