On the Combination of Auditory and Modulation Frequency Channels for ASR applications

Hynek Hermansky, Fabio Valente

This paper investigates the combination of evidence coming from different frequency channels obtained filtering the speech signal at different auditory and modulation frequencies. In our previous work \cite{icassp2008}, we showed that combination of classi ...

Hierarchical and Parallel Processing of Modulation Spectrum for ASR applications

Hynek Hermansky, Fabio Valente

The modulation spectrum is an efficient representation for describing dynamic information in signals. In this work we investigate how to exploit different elements of the modulation spectrum for extraction of information in automatic recognition of speech ...

30-km spontaneous-Brillouin distributed temperature sensor employing Simplex-coding and low optical input power

Marcelo Alfonso Soto Hernandez

In this work we have applied optical pulse-coding technique to spontaneous Brillouin-based distributed temperature sensor (BDTS) based on the Landau-Placzek ratio (LPR). We experimentally show that pulse-coding applied to optical time domain reflectometry ...

An automatic pulse alignment method for slope controlled super-regenerative receiver systems

Catherine Dehollain, Michel Declercq

Recently there is an increase in interest for using super-regenerative receivers for pulse based communication systems. To receive a pulse using the super-regenerative architecture the pulse needs to be aligned with the zero crossing of the damping co-effi ...

Low delay video coding

Analogue wireless cameras have been employed for decades, however they have not become an universal solution due to their difficulties of set up and use. The main problem is the link robustness which mainly depends on the requirement of a line-of-sight vie ...

Audio Coding Based on Long Temporal Contexts

Petr Motlicek, Hynek Hermansky

We describe novel audio coding technique designed to be utilized at medium bit-rates. Unlike classical state-of-the-art audio coders that are based on short-term spectra, our approach uses relatively long temporal segments of audio signal in critical-band- ...

Contrôle sensorless de moteur asynchrone

Le but du projet est de réaliser la commande d'un moteur asynchrone sans capteur et d'en évaluer les performances. La plateforme utilisée pour implémenter l'algorithme de contrôle est un DSP (Digital Signal Processor) de la famille 2812 de Texas Instrument ...

On the significance of binning in a scaling-law sense

Michael Christoph Gastpar

An efficient distributed source coding system with two encoders and dependent data streams must remove two kinds of redundancy: redundancy in each stream and between the two streams. The striking result of Slepian and Wolf showed that the latter can be eli ...

Efficient error correction solutions for OFDM based digital video

Mauro Lattuada

The robustness of the delivery of digital compressed video streams has always been one of the main topic of the standardization bodies to assure the Quality of the Service (QoS). The MPEG standard which is nowadays the reference for digital television defi ...
