Physical-layer (PHY) security is widely used as an effective method for ensuring secure wireless communications. However, when the legitimate user (LU) and eavesdropper (Eve) are in close proximity, channel coupling can significantly degrade performance of PHY. Frequency diverse array (FDA) technique addresses issues by introducing frequency offsets among elements. FDA’s ability to communication relies mainly on domain characteristics, lacking spatial degrees freedom. The recently proposed...
Joint admission control and power minimization are critical challenges in intelligent reflecting surface (IRS)-assisted networks. Traditional methods often rely on <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">l</i> <sub xmlns:xlink="http://www.w3.org/1999/xlink">1</sub> -norm approximations alternating optimization (AO) techniques, which suffer from high computational complexity lack robust convergence guarantees. To address these...
In this study, we examine the impact of information-driven awareness on spread an epidemic from perspective resource allocation by comprehensively considering a series realistic scenarios. A coupled awareness-resource-epidemic model top multiplex networks is proposed, and Microscopic Markov Chain Approach adopted to study complex interplay among processes. Through theoretical analysis, infection density predicted precisely, approximate threshold derived. Combining both numerical calculations...
In this paper, we study the multiple-input multiple-output (MIMO) radar transmit waveform design method for beampattern matching. The purpose is to approximate actual one and minimize cross-correlation sidelobes under constant modulus constraint (CMC). Due CMC, problem non-convex, existing methods solve it with relaxation, resulting in performance degradation. Different from these methods, notice that CMC product of complex circles (CC). Based on physical characteristic, direct matching...
In this paper, we study the joint admission control and beamforming problem within a network where one multi-antenna base station tries to serve multiple single-antenna users. Unlike most existing studies which merely identify users that should be denied, our work further suggest better positions in neighbouring area for them previously-rejected are allowed access network. To address this, assume knowledge of channel vectors coverage area, then jointly optimize transmit beamformer vector...
This paper focus on the waveform design of multiple-input multiple-output (MIMO) under practical constraint constant modulus (CM), aims to maximize Signal-to-Interference-plus-Noise Ratio (SINR) radar receiver output in worst case by radiation nulls generation. Because CM constraint, issue is nonconvex and NP-hard. We find that Limited-memory BFGS algorithm suitable for solving quadratic optimization problem equal feasible set complex circle manifold. Numerical results demonstrate our method...
The Multiple-Input Multiple-Output (MIMO) radar transmit beampattern matching under the Constant Modulus Constraint (CMC) is a key technology. Most existing approaches address this problem by relaxation, which result in performance degradation. Different from these methods, we notice that CMC product of complex circles. Based on characterisic, Riemannian Complex Circle Manifold (RCCM) method without relaxation developed. More precisely, aforementioned firstly reformulated as an unconstraint...
This work considers MIMO radar waveform design with robust interference suppression capability in scenarios where signal is independent to interference. The caused a quadratic optimization problem by designing transmit beampattern deep radiation notches the selected directions, under CM constraint. Then, we propose novel Riemannian Trust Region (RTR) method on complex circle manifold for solving this relatively cheap computational cost. Numerical results show our has better performance...
