Joint Estimation of Clustered User Activity and Correlated Channels with Unknown Covariance in mMTC
Hamza Djelouat, Markus Leinonen, Markku Juntti
This paper considers joint user identification and channel estimation (JUICE) in grant-free access with a \emph{clustered} user activity pattern. In particular, we address the JUIC…
Joint Coherent and Non-Coherent Detection and Decoding Techniques for Heterogeneous Networks
Leatile Marata, Onel Luis Alcaraz López, Hamza Djelouat +3
Cellular networks that are traditionally designed for human-type communication (HTC) have the potential to provide cost effective connectivity to machine-type communication (MTC).…
Leveraging Deep Neural Networks for Massive MIMO Data Detection
Ly V. Nguyen, Nhan T. Nguyen, Nghi H. Tran +3
Massive multiple-input multiple-output (MIMO) is a key technology for emerging next-generation wireless systems. Utilizing large antenna arrays at base-stations, massive MIMO enabl…
Power Control for Multigroup Multicast Cell-Free Massive MIMO Downlink
Muhammad Farooq, Markku Juntti, Le-Nam Tran
We consider a multigroup multicast cell-free multiple-input multiple-output (MIMO) downlink system with short-term power constraints. In particular, the normalized conjugate beamfo…
DQN-based Beamforming for Uplink mmWave Cellular-Connected UAVs
Susarla Praneeth, Gouda Bikshapathi, Deng Yansha +3
Unmanned aerial vehicles (UAVs) are the emerging vital components of millimeter wave (mmWave) wireless systems. Accurate beam alignment is essential for efficient beam-based mmWave…
Beyond 5G RIS mmWave Systems: Where Communication and Localization Meet
Jiguang He, Fan Jiang, Kamran Keykhosravi +3
Upcoming beyond fifth generation (5G) communications systems aim at further enhancing key performance indicators and fully supporting brand new use cases by embracing emerging tech…
