A Variational Bayesian Perspective on Massive MIMO Detection
Duy H. N. Nguyen, Italo Atzeni, Antti Tölli +1
Optimal data detection in massive multiple-input multiple-output (MIMO) systems requires prohibitive computational complexity. A variety of detection algorithms have been proposed…
Coded Caching and Spatial Multiplexing Gain Trade-off in Dynamic MISO Networks
Milad Abolpour, MohammadJavad Salehi, Antti Tolli
The global caching gain of multi-antenna coded caching techniques can be also mostly achieved in dynamic network setups, where the cache contents of users are dictated by a central…
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…
Hybrid Beamforming for mm-Wave Massive MIMO Systems with Partially Connected RF Architecture
Mohammad Majidzadeh, Jarkko Kaleva, Nuutti Tervo +3
To satisfy the capacity requirements of future mobile systems, under-utilized millimeter wave frequencies can be efficiently exploited by employing massive MIMO technology with hig…
DoF Analysis in a Two-Layered Heterogeneous Wireless Interference Network
Meghana Bande, Venugopal Veeravalli, Antti Tolli +1
Degrees of freedom (DoF) is studied in the downlink of a heterogenous wireless network modeled as a two-layered interference network. The first layer of the interference network is…
