Optimal UCA Design for OAM Based Wireless Backhaul Transmission
Haiyue Jing, Wenchi Cheng, Wei Zhang +1
Orbital angular momentum (OAM), which is considered as a novel way to achieve high capacity, has been attracted much attention recently. OAM signals emitted by uniform circular arr…
Cost-Efficient RIS-Aided Channel Estimation via Rank-One Matrix Factorization
Wei Zhang, Wee Peng Tay
A reconfigurable intelligent surface (RIS) consists of massive meta elements, which can improve the performance of future wireless communication systems. Existing RIS-aided channel…
Hierarchical Passive Beamforming for Reconfigurable Intelligent Surface Aided Communications
Chang Cai, Xiaojun Yuan, Wenjing Yan +3
In reconfigurable intelligent surfaces (RISs) aided communications, the existing passive beamforming (PB) design involves polynomial complexity in the number of reflecting elements…
Channel Fingerprint Based Beam Tracking for Millimeter Wave Communications
Ruichen Deng, Sheng Chen, Sheng Zhou +2
Beamforming structures with fixed beam codebooks provide economical solutions for millimeter wave (mmWave) communications due to the low hardware cost. However, the training overhe…
On-off Analog Beamforming for Massive MIMO
Shengli Zhang, Chongtao Guo, Taotao Wang +1
This paper investigates a new analog beamforming architecture for massive multiple-input multiple-output (MIMO) systems, where each of the multiple transmit antennas is switched to…
On Designs of Full Diversity Space-Time Block Codes for Two-User MIMO Interference Channels
Long Shi, Wei Zhang, Xiang-Gen Xia
In this paper, a design criterion for space-time block codes (STBC) is proposed for two-user MIMO interference channels when a group zero-forcing (ZF) algorithm is applied at each…
