In this paper, we consider the problem of full-duplex covert millimeter wave (mmWave)
communications, where a mmWave transmitter (Alice) sends information signals to its …

Edge computing has been considered as a promising solution for enabling computation-
intensive yet latency-sensitive applications at resource-constrained wireless devices (WDs) …

We introduce a general framework for large-scale model-based derivative-free optimization
based on iterative minimization within random subspaces. We present a probabilistic worst …

Intelligent reflecting surfaces (IRSs) are promising enablers for high-capacity wireless
communication systems by constructing favorable channels between the transmitter and …

Fog-cloud computing is one of cores techniques in wireless networks, where fog and cloud
nodes provide high-speed and large-scale computing services to mobile users through a …

Random embeddings project high-dimensional spaces to low-dimensional ones; they are
careful constructions which allow the approximate preservation of key properties, such as …

In this work, we concentrate on designing the precoder for the multiple-input multiple-output
(MIMO) dual functional radar-communication (DFRC) system, where the dual-functional …

In this paper, we propose a secure unmanned aerial vehicle (UAV) communication system
with the assistance of a reconfigurable intelligent surface (RIS), where the design of the UAV …

We propose a general random subspace framework for unconstrained nonconvex
optimization problems that requires a weak probabilistic assumption on the subspace …

The smoothness of graph signals has found desirable real applications for processing
irregular (graph-based) signals. When the latent sources of the mixtures provided to us as …
