Reed Muller (RM) codes are known for their good minimum distance. One can use their structure to construct polar-like codes with good distance properties by choosing the information set as the rows of the polarization matrix with the highest Hamming weight, instead of the most reliable synthetic channels. However, the information length options of ...
Increase data rate while having low power consumption and low computational complexity at the receiver are the key elements for the research in wireless communication for low complexity devices. Sub Terahertz (SubTHz) radio-frequency domain can support ultra-wideband (UWB) communications, and thus the unprecedented increase in the wireless network ...

Memristors enable the computation of matrix-vector multiplications (MVM) in memory and, therefore, show great potential in highly increasing the energy efficiency of deep neural network (DNN) inference accelerators. However, computations in memristors suffer from hardware non-idealities and are subject to different sources of noise that may negativ...
Efficient strategies for non-destructive testing of damaged composite laminates modeled from homogenization of fiber-reinforced polymers could in- volve fused data. Here, those are from electromagnetic and infrared thermographic modalities, for which semi-analytical models of the interaction are available. Focus is on inter-layer delaminations. Pat...
Convolutional Neural Network (CNN) have been widely used in image classification. Over the years, they have also benefited from various enhancements and they are now considered as state of the art techniques for image like data. However, when they are used for regression to estimate some function value from images, fewer recommendations are availab...
La sécurité des zones sensibles contre les menaces de drones est devenue un enjeu majeur. Dans ce contexte, les radars multistatiques présentent des avantages significatifs par rapport aux radars monostatiques en raison de l'exploitation de la diversité spatiale et d'une meilleure détectabilité des cibles. Ainsi, le placement des capteurs a un impa...
De nombreuses techniques de focalisation sont utilisées pour établir la réponse en distance avec un radar OFDM (Orthogonal Frequency Division Multiplex). Les plus connues parmi elles sont le filtre adapté (ou matched filter, MF) et le forçage à zéro (ou zero forcing, ZF). Cet article compare les grandeurs de PSLR (Peak Side Lobe Ratio) et ISLR (Int...
Single Image Super Resolution (SISR) methods aim to recover the clean images in high resolution from low resolution observations.A family of patch-based approaches have received considerable attention and development. The minimum mean square error (MMSE) methodis a powerful image restoration method that uses a probability model on the patches of im...
Hyperspectral imaging is a major tool in modern science, which relies on a compromise between spatial resolution, spectral resolution, and imaging speed. Inspired by single-pixel imaging, we propose a versatile system that enables the fast acquisition of highspectral-resolution hypercubes. Our computational hyperspectral imaging device is composed ...
