Exploiting Temporal Context in High-Resolution Movement-Related EEG Classification 

Doležal, Jaromír; Šťastný, Jakub; Sovka, Pavel (Společnost pro radioelektronické inženýrství, 2011-09)
The contribution presents an application of a movement-related EEG temporal development classification which improves the classification score of voluntary movements controlled by closely localized regions of the brain. A ...

Detection of Cortical Oscillations Induced by SCS Using Power Spectral Density 

Svoboda, L.; Stancak, A.; Sovka, Pavel (Společnost pro radioelektronické inženýrství, 2007-12)
Chronic, intractable pain of lower back and lower extremity might develop as the result of unsuccessful surgery of back. This state called failed-back surgery syndrome (FBSS) cannot be effectively treated by pharmacotherapy. ...

ICA Model Order Estimation Using Clustering Method 

Ruckay, L.; Šťastný, Jakub; Sovka, Pavel (Společnost pro radioelektronické inženýrství, 2007-12)
In this paper a novel approach for independent component analysis (ICA) model order estimation of movement electroencephalogram (EEG) signals is described. The application is targeted to the brain-computer interface (BCI) ...

Localization of Cortical Oscillations Induced by SCS Using Coherence 

Svoboda, L.; Stancak, A.; Sovka, Pavel (Společnost pro radioelektronické inženýrství, 2007-12)
This paper suggests a method based on coherence analysis and scalp mapping of coherence suitable for more accurate localization of cortical oscillations induced by electric stimulation of the dorsal spinal cord (SCS), which ...

CAR2 - Czech Database of Car Speech 

Pollak, P.; Vopicka, J.; Hanzl, V.; Sovka, Pavel (Společnost pro radioelektronické inženýrství, 1999-12)
This paper presents new Czech language two-channel (stereo) speech database recorded in car environment. The created database was designed for experiments with speech enhancement for communication purposes and for the study ...

Echo Cancellation II: Double Talk Detection and Environmental Noise Influence 

Brodsky, M.; Sovka, Pavel (Společnost pro radioelektronické inženýrství, 2000-04)
Two problems arising in the real-life application of echo cancellation systems are analysed.The first, simultaneous activity of both telephone users (double talk) deteriorates the echo suppression. The second, environmental ...

A Family of Coherence-Based Multi-Microphone Speech Enhancement Systems 

Pham, Q. H.; Sovka, Pavel (Společnost pro radioelektronické inženýrství, 2003-06)
This contribution addresses the problem of additive noise reduction in speech picked up by a microphone in a noisy environment. Two systems belonging to the family of coherence-based noise cancellers are presented. Suggested ...

Analysis and Simulation of Frost's Beamformer 

Strupl, M.; Sovka, Pavel (Společnost pro radioelektronické inženýrství, 2003-06)
Sensor arrays are often used for a signal separation from noises using the information about the direction of arrival. The aim of this paper is to analyze Frost's beamformer with respect to the speech preprocessing for the ...

ACE Strategy with Virtual Channels 

Vondrasek, M.; Sovka, Pavel; Tichy, T. (Společnost pro radioelektronické inženýrství, 2008-12)
Cochlear implant is an electronic device, which can mediate hearing sensations to profoundly deaf people. Contemporary cochlear implants are sophisticated electronic devices; however, their performance could still be ...

Derivation of Criterion Suitable for Evaluation of Multichannel Noise Reduction Systems for Speech Processing 

Bolom, V.; Ingerle, J.; Sovka, Pavel (Společnost pro radioelektronické inženýrství, 2009-12)
This paper deals with the theoretical derivation of the Noise Reduction criterion suitable for evaluation of multichannel noise reduction system performance. This criterion is suitable for noise suppression assessment and ...
