[hal-01562291] Empirical comparison of Chirp and Multitones on experimental UWB Software Defined Radar prototype

This paper proposes and tests an approach for an unbiased study of radar waveforms' performances. Using the ultrawide band software defined radar prototype, the performances of Chirp and Multitones are compared in range profile and detection range. The architecture was implemented and has performances comparable to the state of the art in software defined radar prototypes. [...]

[hal-01562671] Development and Validation of a Highly Sensitive and Specific Automated Algorithm to Evaluate the Abundance of Bubbles in Small Bowel Capsule Endoscopy


[hal-01556736] A Strong Data Processing Inequality for Thinning Poisson Processes and Some Applications

This paper derives a simple strong data processing inequality (DPI) for Poisson processes: after a Poisson process is passed through p-thinning—in which every arrival remains in the process with probability p and is erased otherwise, independently of the other points—the mutual information between the Poisson process and any other random variable is reduced to no more than p times its original value. [...]

[hal-01556729] Covert Communication with Noncausal Channel-State Information at the Transmitter

We consider the problem of covert communication over a state-dependent channel, where the transmitter has non-causal knowledge of the channel states. Here, " covert " means that the probability that a warden on the channel can detect the communication must be small. [...]

[hal-01556731] Asymptotic Capacity Results for MIMO Wireless Optical Communication

This paper provides several asymptotic capacity results for the multiple-input multiple-output free-space optical intensity channel in the regime of high signal-to-noise ratio (SNR). For the case where the channel matrix has full column rank, the asymptotic capacity is derived assuming a peak-power constraint on each transmit antenna, or an average-power constraint on the total power across all transmit antennas, or both. [...]

[hal-01558617] Analysis of One-Bit Quantized Precoding for the Multiuser Massive MIMO Downlink

—We present a mathematical analysis of linear pre-coders for downlink massive MIMO multiuser systems that employ one-bit digital-to-analog converters at the basestation in order to reduce complexity and mitigate power usage. The analysis is based on the Bussgang theorem, and applies generally to any linear pre-coding scheme. [...]

[hal-01562669] Clinical Usability Quantification Of a Real-Time Polyp Detection Method In Videocolonoscopy


[hal-01549575] Minimum probability-of-error perturbation precoding for the one-bit massive MIMO downlink

Linear precoders have been shown to perform reasonably well at low SNR when the basestation of a MIMO downlink employs one-bit digital-to-analog converters to quantize the pre-coder outputs. However, at medium-to-high SNRs, an error floor is encountered due to the coarse quantization. [...]

[hal-01552359] Wireless and Portable System for the Study of in-vitro Cell Culture Impedance Spectrum by Electrical Impedance Spectroscopy

A wireless and portable system, consisting in an electronic board and a computer software graphical interface, is presented in this article as a feasible way to do in-vitro electric bioimpedance spectroscopy of cells. It is designed to work inside a culture chamber performing impedance measurement in the frequency range of 64Hz to 200KHz. [...]

[hal-01542290] Récupération d'énergie dans la bande RFID UHF pour capteurs connectés

La gestion de stocks à l’aide de tags RFID, pratique aujourd’hui courante, permet un gain de temps et de visibilité sur les activités logistiques, de l’approvisionnement à la vente des produits. Si dans certains secteurs économiques, la simple consultation par voie RFID de l’identifiant d’un produit suffit à la gestion du stock, dans d’autres secteurs, des informations plus riches relatives à l’état du produit sont nécessaires. [...]
