Near-Field Beampointing with Low Exposure Regions: a Dominant Subspace Projection Approach
Laurence Defraigne, Gilles Monnoyer, Jérôme Louveaux +1
The spherical nature of the wavefronts exhibited in the near-field of antenna arrays enables advanced beamforming capabilities, such as beampointing and beamnulling. In this paper,…
Aliasing in Near-Field Array Ambiguity Functions: a Spatial Frequency-Domain Framework
Gilles Monnoyer, Jérôme Louveaux, Laurence Defraigne +2
Next-generation communication and localization systems increasingly rely on extremely large-scale arrays (XL-arrays), which promise unprecedented spatial resolution and new functio…
Chirp-Based Aliasing Analysis of Arrays in the Spherical Wavefront Regime
Gilles Monnoyer, Laurence Defraigne, Baptiste Sambon +2
In antenna arrays, wave propagation modeling based on Euclidean principles is typically represented by steering vectors or signals. This paper provides a new, chirp-based, interpre…
Cellular Load Dependent Sleep Control for Energy Efficient HetNets with Non-Uniform User Distributions
Martin Willame, Charles Wiame, Jérôme Louveaux +2
This study proposes a novel stochastic geometry framework analyzing power control strategies in spatially correlated network topologies. Heterogeneous networks are studied, with us…
Multistatic OFDM Radar Fusion of MUSIC-based Angle Estimation
Martin Willame, Hasan Can Yildirim, Laurent Storrer +2
This study investigates the problem of angle-based localization of multiple targets using a multistatic OFDM radar. Although the maximum likelihood (ML) approach can be employed to…
Implementing a LoRa Software-Defined Radio on a General-Purpose ULP Microcontroller
Mathieu Xhonneux, Jérôme Louveaux, David Bol
Emerging Internet-of-Things sensing applications rely on ultra low-power (ULP) microcontroller units (MCUs) that wirelessly transmit data to the cloud. Typical MCUs nowadays consis…
CSI-based versus RSS-based Secret-Key Generation under Correlated Eavesdropping
François Rottenberg, Trung-Hien Nguyen, Jean-Michel Dricot +2
Physical-layer security (PLS) has the potential to strongly enhance the overall system security as an alternative to or in combination with conventional cryptographic primitives us…
A Blind Beam Tracking Scheme for Millimeter Wave Systems
Steve Blandino, Thibault Bertrand, Claude Desset +2
Millimeter-wave is one of the technologies powering the new generation of wireless communication systems. To compensate the high path-loss, millimeter-wave devices need to use high…
Secrecy Capacity of FBMC-OQAM Modulation over Frequency Selective Channel
François Rottenberg, Philippe De Doncker, François Horlin +1
This paper studies the information-theoretic secrecy capacity of an Offset-QAM-based filterbank multicarrier (FBMC-OQAM) communication over a wiretap frequency selective channel. T…
Impact of Realistic Propagation Conditions on Reciprocity-Based Secret-Key Capacity
François Rottenberg, Philippe De Doncker, François Horlin +1
Secret-key generation exploiting the channel reciprocity between two legitimate parties is an interesting alternative solution to cryptographic primitives for key distribution in w…
A Low-Complexity LoRa Synchronization Algorithm Robust to Sampling Time Offsets
Mathieu Xhonneux, Orion Afisiadis, David Bol +1
LoRaWAN is nowadays one of the most popular protocols for low-power Internet-of-Things communications. Although its physical layer, namely LoRa, has been thoroughly studied in the…
Comments on "Probabilities of Error for Adaptive Reception of M-Phase Signals"
Trung-Hien Nguyen, Jerome Louveaux, Philippe De Doncker +1
Paper [1] derived the probability density function (PDF) of a sum of products of two correlated complex Gaussian zero-mean random variables (RVs) that has been applied to calculate…
Frequency-Domain Time-Reversal Precoding in Wideband MISO OFDM Communication Systems
Trung-Hien Nguyen, Jean-François Determe, Mathieu Van Eeckhaute +3
Time reversal (TR) recently emerged as an interesting communication technology capable of providing a good spatio-temporal signal focusing effect. New generations of large-bandwidt…
Quantity over Quality: Dithered Quantization for Compressive Radar Systems
Thomas Feuillen, Chunlei Xu, Jérôme Louveaux +2
In this paper, we investigate a trade-off between the number of radar observations (or measurements) and their resolution in the context of radar range estimation. To this end, we…
