A General Coding Framework for Adaptive Private Information Retrieval
Jinbao Zhu, Xiaohu Tang
The problem of -colluding private information retrieval (PIR) enables the user to retrieve one out of files from a distributed storage system with servers without reveal…
Multi-Satellite Cooperative Networks: Joint Hybrid Beamforming and User Scheduling Design
Xuan Zhang, Shu Sun, Meixia Tao +2
In this paper, we consider a cooperative communication network where multiple low-Earth-orbit (LEO) satellites provide services to multiple ground users (GUs) cooperatively at the…
Enhanced Low-Redundancy Restricted Array for Direction of Arrival Estimation
Shidong Zhang, Zhengchun Zhou, Guolong Cui +2
Sensor arrays play a significant role in direction of arrival (DOA) estimation. Specifically, arrays with low redundancy and reduced mutual coupling are desirable. In this paper, w…
Scalable Cell-Free Massive MIMO Systems with Finite Resolution ADCs/DACs over Spatially Correlated Rician Fading Channels
Xiangjun Ma, Xianfu Lei, P. Takis Mathiopoulos +2
In this paper, an analytical framework for evaluating the performance of scalable cell-free massive MIMO (SCF-mMIMO) systems in which all user equipments (UEs) and access points (A…
