In this article we consider authentication at the physical layer, in which the authenticator
aims at distinguishing a legitimate supplicant from an attacker on the basis of the …

Wireless physical layer security has attracted great attention in recent years. Although
mobility is an intrinsic property of wireless networks, most of the existing works only consider …

This book introduces the theoretical elements at the basis of various classes of algorithms
commonly employed in the physical layer (and, in part, in MAC layer) of wireless …

The performance of existing moments-based non-data-aided (NDA) estimators of signal-to-
noise ratio (SNR) in digital communication systems substantially degrades with multilevel …

Dynamic spectrum access (DSA) is the key to solving worldwide spectrum shortage. The
open wireless medium subjects DSA systems to unauthorized spectrum use by illegitimate …

Deep learning (DL) is applied to predict signal-to-noise ratio (SNR) in de facto LTE and 5G
systems in a non-data-aided (NDA) manner. Various channel conditions and impairments …

In this paper, we propose the adaptive modulation (AM) model based on machine learning
for a multiple-input multiple-output (MIMO) orthogonal frequency-division multiplexing …

Cognitive Radio (CR), a hierarchical Dynamic Spectrum Access (DSA) model, has been
considered as a strong candidate for future communication systems improving spectrum …

High-accuracy positioning enables emerging of new vertical markets for the forthcoming fifth
generation (5G) mobile networks. In this paper, we study network-side positioning and …

This work deals with the block-sparse system identification problem on the basis of the
maximum correntropy criterion (MCC). The MCC is known for its robustness against non …
