User Activity Detection and Channel Estimation of Spatially Correlated Channels via AMP in Massive MTC
Hamza Djelouat, Leatile Marata, Markus Leinonen +2
This paper addresses the problem of joint user identification and channel estimation (JUICE) for grant-free access in massive machine-type communications (mMTC). We consider the JU…
Minimizing AoI in Resource-Constrained Multi-Source Relaying Systems with Stochastic Arrivals
Abolfazl Zakeri, Mohammad Moltafet, Markus Leinonen +1
We consider a multi-source relaying system where the sources independently and randomly generate status update packets which are sent to the destination with the aid of a bufferaid…
Exploiting Spatial Correlation for Pilot Reuse in Single-Cell mMTC
Lucas Ribeiro, Markus Leinonen, Hanan Al-Tous +2
As a key enabler for massive machine-type communications (mMTC), spatial multiplexing relies on massive multiple-input multiple-output (mMIMO) technology to serve the massive numbe…
Spatial Correlation Aware Compressed Sensing for User Activity Detection and Channel Estimation in Massive MTC
Hamza Djelouat, Markus Leinonen, Markku Juntti
Grant-free access is considered as a key enabler to massive machine-type communications (mMTC) as it promotes energy-efficiency and small signalling overhead. Due to the sporadic u…
Iterative Reweighted Algorithms for Joint User Identification and Channel Estimation in Spatially Correlated Massive MTC
Hamza Djelouat, Markus Leinonen, Markku Juntti
Joint user identification and channel estimation (JUICE) is a main challenge in grant-free massive machine-type communications (mMTC). The sparse pattern in users' activity allows…
Moment Generating Function of the AoI in Multi-Source Systems with Computation-Intensive Status Updates
Mohammad Moltafet, Markus Leinonen, Marian Codreanu
We consider a multi-source status update system in which status updates are transmitted as packets containing the measured value of the monitored process and a time stamp represent…
