Z3RO Precoder Canceling Nonlinear Power Amplifier Distortion in Large Array Systems
François Rottenberg, Gilles Callebaut, Liesbet Van der Perre
Large array-based transmission uses the combination of a massive number of antenna elements and clever precoder designs to achieve array gain and spatially multiplex different user…
Spatial Distribution of Distortion due to Nonlinear Power Amplification in Distributed Massive MIMO
François Rottenberg, Gilles Callebaut, Liesbet Van der Perre
Due to the nonlinearity of power amplifiers (PAs), the transmit signal is distorted. Previous works have studied the spatial distribution of this distortion for a central massive M…
Experimental Exploration of Unlicensed Sub-GHz Massive MIMO for Massive Internet-of-Things
Gilles Callebaut, Sara Gunnarsson, Andrea P. Guevara +3
Due to the increase of Internet-of-Things (IoT) devices, IoT networks are getting overcrowded. Networks can be extended with more gateways, increasing the number of supported devic…
A Primer on Techtile: An R&D Testbed for Distributed Communication, Sensing and Positioning
Gilles Callebaut, Jarne Van Mulders, Geoffrey Ottoy +1
The Techtile measurement infrastructure is a multi-functional, versatile testbed for new communication and sensing technologies relying on fine-grained distributed resources. The f…
Energy Neutral Devices: Can Hybrid RF Acoustic Signals Point Them Out?
Bert Cox, Chesney Buyle, Liesbet Van der Perre +1
We present a hybrid signaling approach to position energy-neutral devices. Our method combines the best of two worlds: instant RF signals for both communication and energy transfer…
Massive MIMO goes Sub-GHz: Implementation and Experimental Exploration for LPWANs
Gilles Callebaut, Sara Gunnarsson, Andrea P. Guevara +4
Low-Power Wide-Area Networks operating in the unlicensed bands are being deployed to connect a rapidly growing number of Internet-of-Things devices. While the unlicensed sub-GHz ba…
