5G wireless communication systems provide massive system capacity with high data rates,
very short low-latency, and ultra-high reliability, in addition to high connection density with a …

Millimeter wave (mmWave) and terahertz (THz) radio access technologies (RAT) are
expected to become a critical part of the future cellular ecosystem providing an abundant …

Physical layer protection, which protects data confidentiality using information-theoretic
methods, has recently attracted a lot of research attention. Using the inherent randomness of …

Abstract The Internet of Vehicles (IoV) is employed to gather real-time traffic information for
drivers, and base stations in 5G systems are used to assist in traffic data transmission. For …

Location-aided beam alignment methods exploit the user location and prior knowledge of
the propagation environment to identify the beam directions that are more likely to maximize …

Millimeter-wave (mmW) spectrum is a major candidate to support the high data rates of 5G
systems. However, due to directionality of mmW communication systems, misalignments …

Covert communication prevents legitimate transmission from being detected by a warden
while maintaining certain covert rate at the intended user. Prior works have considered the …

Swift and accurate alignment of transmitter (Tx) and receiver (Rx) beams is a fundamental
design challenge to enable the reliable outdoor millimeter-wave communications. In this …

In this paper, we study the problem of beam alignment for millimeter wave (mmWave)
communications, where a hybrid analog and digital beamforming structure is employed at …

Position-aided beam selection methods have been shown to be an effective approach to
achieve high beamforming gain while limiting the overhead and latency of initial access in …
