Device Detection and Channel Estimation in MTC with Correlated Activity Pattern
Hamza Djelouat, Mikko J. Sillanpää, Markku Juntti
This paper provides a solution for the activity detection and channel estimation problem in grant-free access with correlated device activity patterns. In particular, we consider a…
Hierarchical MTC User Activity Detection and Channel Estimation with Unknown Spatial Covariance
Hamza Djelouat, Mikko J. Sillanpää, Markus Leinonen +1
This paper addresses the joint user identification and channel estimation (JUICE) problem in machine-type communications under the practical spatially correlated channels model wit…
Sequential model correction for nonlinear inverse problems
Arttu Arjas, Mikko J. Sillanpää, Andreas Hauptmann
Inverse problems are in many cases solved with optimization techniques. When the underlying model is linear, first-order gradient methods are usually sufficient. With nonlinear mod…
