Joint time and beam domain non-orthogonal multiple access [PDF]
Tongxin xuebao, 2021 In order to improve the system’s ability to accommodate connected devices, a joint time and beam domain non-orthogonal multiple access (NOMA) scheme was proposed, which was suitable for millimeter wave massive multiple-input multiple-output (MIMO ...

Structure Radio Beam Construction in Azimuthal Domain [PDF]
IEEE Access, 2020 Structure radio beams with diverse radiation patterns exhibit huge potentials in many applications. In this paper, we propose a plane spiral orbital angular momentum (PS-OAM) based structure radio beam construction scheme, in which several PS-OAM waves ...

A Multi-Frequency Tomographic Inverse Scattering Using Beam Basis Functions
Sensors, 2022 We present an overview of a beam-based approach to ultra-wide band (UWB) tomographic inverse scattering, where beam-waves are used for local data-processing and local imaging, as an alternative to the conventional plane-wave and Green’s function ...

Joint Deblurring and Denoising of THz Time-Domain Images
IEEE Access, 2021 Terahertz (THz) pulse/time-domain imaging attracted increased interest in recent years mostly due to its ability to extract dielectric properties of sample materials (i.e., absorption coefficient and the refraction index) from the amplitude and phase of ...

Study on Coupled Vertical Vehicle-Bridge Dynamic Performance of Medium and Low-Speed Maglev Train
Applied Sciences, 2021 The levitation stability of maglev trains is determined by the interaction of vehicle-bridge dynamic characteristics. The state change of vehicle and track beam will affect the dynamic performance of maglev trains.
