Optimization of Super-Directive Linear Arrays with Differential Evolution for High Realized Gain
In this paper, we assert that it is crucial to consider the trade-off between directivity and overall efficiency (to achieve high realized gain) before employing super-directive arrays in real-world applications.
Super-Directive Antenna Arrays: How Many Elements Do We Need?
Thus, it is observed that super-directivity can be obtained in an array with a maximum of five elements.
A Hypernetwork Based Framework for Non-Stationary Channel Prediction
In this paper, a hypernetwork based framework is proposed for non-stationary channel prediction.
Joint Power Optimization and AP Selection for Secure Cell-Free Massive MIMO
In this paper, we investigate joint power control and access point (AP) selection scheme in a cell-free massive multiple-input multiple-output (CF-mMIMO) system under an active eavesdropping attack, where an eavesdropper tries to overhear the signal sent to one of the legitimate users by contaminating the uplink channel estimation.
How Does Cell-Free Massive MIMO Support Multiple Federated Learning Groups?
Federated learning (FL) has been considered as a promising learning framework for future machine learning systems due to its privacy preservation and communication efficiency.
Intelligent Reflecting Surfaces at Terahertz Bands: Channel Modeling and Analysis
An intelligent reflecting surface (IRS) at terahertz (THz) bands is expected to have a massive number of reflecting elements to compensate for the severe propagation losses.
Intelligent Reflecting Surfaces with Spatial Modulation: An Electromagnetic Perspective
Using a secondary source present in a wireless communication environment, such as a backscatter tag, it is possible to leverage the incoming radiation from the source as a reference-wave to synthesize the desired wavefront across the reflecting surface, radiating a field of interest.
The Road to 6G: Ten Physical Layer Challenges for Communications Engineers
While the deployment of 5G cellular systems will continue well in to the next decade, much interest is already being generated towards technologies that will underlie its successor, 6G.
Deep Energy Autoencoder for Noncoherent Multicarrier MU-SIMO Systems
We propose a novel deep energy autoencoder (EA) for noncoherent multicarrier multiuser single-input multipleoutput (MU-SIMO) systems under fading channels.

DYVERSE: DYnamic VERtical Scaling in Multi-tenant Edge Environments
When compared to executing applications on the Edge servers without dynamic vertical scaling, static priorities and dynamic priorities reduce SLO violation rates of requests by up to 4% and 12% for the online game, respectively, and in both cases 6% for the face detection workload.

A New Look at Dual-Hop Relaying: Performance Limits with Hardware Impairments
Such approximations make sense in low-rate systems, but can lead to very misleading results when analyzing future high-rate systems.
