Enhanced Fairness and Scalability of Power Control Schemes in Multi-Cell Massive MIMO
Amin Ghazanfari, Hei Victor Cheng, Emil Björnson +1
This paper studies the transmit power optimization in multi-cell massive multiple-input multiple-output (MIMO) systems. Network-wide max-min fairness (NW-MMF) and network-wide prop…
A Fair and Scalable Power Control Scheme in Multi-cell Massive MIMO
Amin Ghazanfari, Hei Victor Cheng, Emil Björnson +1
This paper studies the transmit power optimization in a multi-cell massive multiple-input multiple-output (MIMO) system. To overcome the scalability issue of network-wide max-min f…
Learning Class Unique Features in Fine-Grained Visual Classification
Runkai Zheng, Zhijia Yu, Yinqi Zhang +3
A major challenge in Fine-Grained Visual Classification (FGVC) is distinguishing various categories with high inter-class similarity by learning the feature that differentiate the…
Stochastic Transceiver Optimization in Multi-Tags Symbiotic Radio Systems
Xihan Chen, Hei Victor Cheng, Kaiming Shen +2
Symbiotic radio (SR) is emerging as a spectrum- and energy-efficient communication paradigm for future passive Internet-of-things (IoT), where some single-antenna backscatter devic…
Power Control for Massive MIMO Systems with Nonorthogonal Pilots
Xihan Chen, Kaiming Shen, Hei Victor Cheng +3
This letter shows that optimizing the transmit powers along with optimally designed nonorthogonal pilots can significantly reduce pilot contamination and improve the overall throug…
Joint Design of Measurement Matrix and Sparse Support Recovery Method via Deep Auto-encoder
Shuaichao Li, Wanqing Zhang, Ying Cui +2
Sparse support recovery arises in many applications in communications and signal processing. Existing methods tackle sparse support recovery problems for a given measurement matrix…
