Interference is traditionally viewed as a performance limiting factor in wireless
communication systems, which is to be minimized or mitigated. Nevertheless, a recent line of …

Non-orthogonal multiple access (NOMA) has been widely recognized as a promising way to
scale up the number of users, enhance the spectral efficiency, and improve the user-fairness …

While the emerging 6G networks are anticipated to meet the high-end service quality
demands of the mobile edge users in terms of data rate and delay satisfaction, new attack …

Nonorthogonal multiple access (NOMA) assisted semi-grant-free transmission admits grant-
free users to access the channels otherwise solely occupied by grant-based users, and has …

Malicious jamming launched by smart jammers can attack legitimate transmissions, which
has been regarded as one of the critical security challenges in wireless communications …

Key generation from the randomness of wireless channels is a promising alternative to
public key cryptography for the establishment of cryptographic keys between any two users …

The Internet of Things (IoT) realizes a vision where billions of interconnected devices are
deployed just about everywhere, from inside our bodies to the most remote areas of the …

Physical layer security (PLS) has been extensively explored as an alternative to
conventional cryptographic schemes for securing wireless links. Many studies have shown …

This paper investigates the physical layer security of a satellite network, whose downlink
spectral resource is shared with a terrestrial cellular network. We propose to employ a multi …

The evolving explosion in high data rate services and applications will soon require the use
of untapped, abundant unregulated spectrum of the visible light for communications to …
