MIMO in tunnel: impact of polarization and array orientation on the channel characteristics

Frédéric Challita, Pierre Laly, M. Lienard, Davy Gaillot, Pierre Degauque, Jose-Maria Molina-Garcia-Pardo, Wout Joseph

Polarimetric characteristics of the propagation channel in a straight tunnel and in a frequency band around 1.3 GHz, are deduced from measurements using a real-time MIMO channel sounder. Emphasis is on the cross-polarization discrimination factor and, for a MIMO configuration, on the correlation…

Low-complexity feature extraction unit for “Wake-on-Feature” speech processing

Simon Lecoq, Jean Le Bellego, Angel Gonzalez, Benoit Larras, Antoine Frappé

In the context of energy-constrained automatic speech recognition, a modeling and simulation tool is presented to evaluate the hardware complexity of a feature extraction unit. The objective is to evaluate the minimal amount of features necessary for voice-activity detection, considering limited…

High-Pass Sub-mm Wave Filtering by Woven Textile Metamaterials

Ludovic Burgnies, Camille Huppe, Guillaume Ducournau, Cedric Cochrane, Francois Rault, Vladan Koncar, Eric Lheurette

Textile metamaterials produced by a weaving of metallic and dielectric yarns are considered for filtering operations in the sub-millimeter hand. A woven metamaterial was designed by parametric simulations aimed at producing a high-pass filter with a cutoff frequency at around 500 GHz above a high-…
