Stringent physical resource constraints in unmanned aerial vehicle (UAV) communications
bring new challenges to energy efficient transmission. In this paper, we study energy …

In heterogeneous cellular networks (HCNs), the interference received at a user is correlated
over time slots since it comes from the same set of randomly located base stations (BSs) …

In this letter, we study the problem of estimating a complex parameter in a wireless sensor
network under individual power constraints and bounded channel uncertainty, where the …

We propose a novel joint channel estimator for a relaying MIMO communication system.
Considering a three-hop relaying protocol, our combined alternating least squares (Comb …

In this letter, we propose a distributed jamming strategy to maximize the achievable ergodic
secrecy rate (ESR) of a single-input multi-output (SIMO) transmission with a multiple …

In this letter, we investigate a sensing assisted communication system employing the
Orthogonal Time Frequency Space (OTFS) waveforms. We first develop a channel sensing …

Many high data-rate video-processing applications are subject to a trade-off between
throughput and the sizes of buffers in the system (the storage distribution). These …

In this work, we investigate the spectral efficiency (SE) and energy efficiency (EE) for a
massive multiple-input multiple-output multi-pair two-way amplify-and-forward relaying …

Multi-antenna technologies have already achieved a series of great successes in the
development of information networks. For future space-ground integrated networks (SGINs) …

Combination of directional modulation (DM) and frequency diverse array (FDA) provides a
novel opportunity for enabling physical layer security because of the enhanced ability of …
