Feedback is Good, Active Feedback is Better: Block Attention Active Feedback Codes
Emre Ozfatura, Yulin Shao, Amin Ghazanfari +3
Deep neural network (DNN)-assisted channel coding designs, such as low-complexity neural decoders for existing codes, or end-to-end neural-network-based auto-encoder designs are ga…
Learning to Perform Downlink Channel Estimation in Massive MIMO Systems
Amin Ghazanfari, Trinh Van Chien, Emil Björnson +1
We study downlink (DL) channel estimation in a multi-cell Massive multiple-input multiple-output (MIMO) system operating in a time-division duplex. The users must know their effect…
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…
Optimized Power Control for Massive MIMO with Underlaid D2D Communications
Amin Ghazanfari, Emil Björnson, Erik G. Larsson
In this paper, we consider device-to-device (D2D) communication that is underlaid in a multi-cell massive multiple-input multiple-output (MIMO) system and propose a new framework f…
Power Control for D2D Underlay in Multi-cell Massive MIMO Networks
Amin Ghazanfari, Emil Björnson, Erik G. Larsson
This paper proposes a new power control and pilot allocation scheme for device-to-device (D2D) communication underlaying a multi-cell massive MIMO system. In this scheme, the cellu…
