Active Sensing for Communications by Learning
Foad Sohrabi, Tao Jiang, Wei Cui +1
This paper proposes a deep learning approach to a class of active sensing problems in wireless communications in which an agent sequentially interacts with an environment over a pr…
Hybrid Analog and Digital Beamforming Design for Channel Estimation in Correlated Massive MIMO Systems
Javad Mirzaei, Shahram ShahbazPanahi, Foad Sohrabi +1
In this paper, we study the channel estimation problem in correlated massive multiple-input-multiple-output (MIMO) systems with a reduced number of radio-frequency (RF) chains. Imp…
Sparse Activity Detection in Multi-Cell Massive MIMO Exploiting Channel Large-Scale Fading
