Rotating ULA-Enabled Computed Tomography for Efficient 3D Spatial Power Spectrum Synthesis: Architecture and Principled Orientation Design
Haocheng Hua, Weidong Mei, Jie Xu +1
This paper proposes an efficient three-dimensional (3D) spatial power spectrum synthesis method by rotating a uniform linear array (ULA) about its center in 3D space. Inspired by c…
Microwave Linear Analog Computers Aided Multiuser Communication: General Impedance Matching and Precoding Optimization
Rujing Xiong, Jie Xu, Rui Zhang
Microwave linear analog computers (MiLACs) have recently emerged as a hardware-efficient solution for implementing multi-antenna communication systems. Unlike existing MiLAC design…
Channel Gain Map Reconstruction Based on Virtual Scatterer Model
He Sun, Lipeng Zhu, Jie Xu +1
This paper proposes an efficient method for modeling and reconstructing the channel gain map (CGM) based on virtual scatterers. Specifically, we develop a virtual scatterer model t…
