Data-Driven Robust Beamforming for Initial Access
Sai Subramanyam Thoota, Joao Vieira, Erik G. Larsson
We consider a robust beamforming problem where large amount of downlink (DL) channel state information (CSI) data available at a multiple antenna access point (AP) is used to impro…
Distributed Signal Processing for Out-of-System Interference Suppression in Cell-Free Massive MIMO
Zakir Hussain Shaik, Erik G. Larsson
Cell-free massive multiple-input-multiple-output (CF-mMIMO) is a next-generation wireless access technology that offers superior coverage and spectral efficiency compared to conven…
Massive MIMO with Cauchy Noise: Channel Estimation, Achievable Rate and Data Decoding
Ziya Gulgun, Erik G. Larsson
We consider massive multiple-input multiple-output (MIMO) systems in the presence of Cauchy noise. First, we focus on the channel estimation problem. In the standard massive MIMO s…
Grant-Free Random Access of IoT devices in Massive MIMO with Partial CSI
Gilles Callebaut, François Rottenberg, Liesbet Van der Perre +1
The number of wireless devices is drastically increasing, resulting in many devices contending for radio resources. In this work, we present an algorithm to detect active devices f…
Activity Detection in Distributed Massive MIMO With Pilot-Hopping and Activity Correlation
Ema Becirovic, Emil Björnson, Erik G. Larsson
Many real-world scenarios for massive machine-type communication involve sensors monitoring a physical phenomenon. As a consequence, the activity pattern of these sensors will be c…
Over-the-Air Computation for Distributed Systems: Something Old and Something New
Zheng Chen, Erik G. Larsson, Carlo Fischione +2
Facing the upcoming era of Internet-of-Things and connected intelligence, efficient information processing, computation, and communication design becomes a key challenge in large-s…
