Channel Estimation By Transmitting Pilots From Reconfigurable Intelligent Surface
Yanze Zhu, Yang Liu, Qingqing Wu +2
Reconfigurable intelligent surface (RIS) is a promising technology for future wireless communication systems. Channel estimation (CE) of RIS device is a critical but also challengi…
Joint Activity Detection and Channel Estimation in Massive Machine-Type Communications with Low-Resolution ADC
Ye Xue, An Liu, Yang Li +2
In massive machine-type communications, data transmission is usually considered sporadic, and thus inherently has a sparse structure. This paper focuses on the joint activity detec…
Decentralized Equalization for Massive MIMO Systems With Colored Noise Samples
Xiaotong Zhao, Mian Li, Bo Wang +3
Recently, the decentralized baseband processing (DBP) paradigm and relevant detection methods have been proposed to enable extremely large-scale massive multiple-input multiple-out…
Once and for All: Scheduling Multiple Users Using Statistical CSI under Fixed Wireless Access
Xin Guan, Zhixing Chen, Yibin Kang +1
Conventional multi-user scheduling schemes are designed based on instantaneous channel state information (CSI), indicating that decisions must be made every transmission time inter…
A Physics-based and Data-driven Approach for Localized Statistical Channel Modeling
Shutao Zhang, Xinzhi Ning, Xi Zheng +3
Localized channel modeling is crucial for offline performance optimization of 5G cellular networks, but the existing channel models are for general scenarios and do not capture loc…
