Swin Transformer-Based CSI Feedback for Massive MIMO
Jiaming Cheng, Wei Chen, Jialong Xu +3
For massive multiple-input multiple-output systems in the frequency division duplex (FDD) mode, accurate downlink channel state information (CSI) is required at the base station (B…
Data-Driven Compressed Sensing for Massive Wireless Access
Yanna Bai, Wei Chen, Feifei Sun +2
The central challenge in massive machine-type communications (mMTC) is to connect a large number of uncoordinated devices through a limited spectrum. The typical mMTC communication…
Deep Joint Source-Channel Coding for CSI Feedback: An End-to-End Approach
Jialong Xu, Bo Ai, Ning Wang +1
The increased throughput brought by MIMO technology relies on the knowledge of channel state information (CSI) acquired in the base station (BS). To make the CSI feedback overhead…
Optimal Sampling of Water Distribution Network Dynamics using Graph Fourier Transform
Zhuangkun Wei, Alessio Pagani, Guangtao Fu +4
Water Distribution Networks (WDNs) are critical infrastructures that ensure safe drinking water. One of the major threats is the accidental or intentional injection of pollutants.…
Enhanced Group Sparse Beamforming for Green Cloud-RAN: A Random Matrix Approach
Yuanming Shi, Jun Zhang, Wei Chen +1
Group sparse beamforming is a general framework to minimize the network power consumption for cloud radio access networks (Cloud-RANs), which, however, suffers high computational c…
Generalized Sparse and Low-Rank Optimization for Ultra-Dense Networks
Yuanming Shi, Jun Zhang, Wei Chen +1
Ultra-dense network (UDN) is a promising technology to further evolve wireless networks and meet the diverse performance requirements of 5G networks. With abundant access points, e…
