  • Mutual Relations between Multiple-Input Linear and Multiple-Feedback 

    Pospisil, J.; Horska, J. (Společnost pro radioelektronické inženýrství, 2000-12)
    State models of multiple-input linear non-autonomous dynamical systems are modified to the autonomous form using a multiple piecewise-linear (PWL) feedback. By such a way the corresponding state models of PWL autonomous ...

  • Methods and Application of Phonetic Label Alignment in Speech Processing Tasks 

    Nouza, J.; Myslivec, M. (Společnost pro radioelektronické inženýrství, 2000-12)
    The paper deals with the problem of automatic phonetic segmentation of speech signals, namely for speech analysis and recognition purposes. Several methods and approaches are described and evaluated from the point of view ...

  • Modulation Schemes for Wireless Access 

    Javornik, T.; Kandus, G.; Vejrazka, F. (Společnost pro radioelektronické inženýrství, 2000-12)
    Four modulation schemes, namely minimum shift keying (MSK), Gaussian minimum shift keying (GMSK), multiamplitude minimum shift keying (MAMSK) and π/4 differential quadrature phase shift keying (π/4-QPSK) are described and ...

  • Suppression of Mixed Noise in the Similar Images by Using Adaptive LMS L-filters 

    Kocur, D.; Hudec, R.; Marchevsky, S. (Společnost pro radioelektronické inženýrství, 2000-12)
    In this paper, several adaptive least mean squares (LMS) location-invariant filter (L-filter) modifications will be described. These filters are based on linear combination of order statistics. The adaptive L-filters are ...

  • Pixel Decimation in Block Matching Techniques 

    Radoczi, P.; Levicky, D. (Společnost pro radioelektronické inženýrství, 2000-12)
    Block motion estimation using full search algorithm is computationally extensive. Previously proposed fast algorithms reduce the computation cost by limiting the number of locations searched. In this paper we present ...

  • Identifying the Deterministic Chaos by Using the Lorenz Maps 

    Kvarda, P. (Společnost pro radioelektronické inženýrství, 2000-12)
    This paper presents an investigation of the deterministic and stochastic chaos. The modified Colpitts oscillator is used as an example of deterministic chaos in electronic circuits. The graphical method of Lorenz maps is ...

  • Fractal Image Coding with Digital Watermarks 

    Candik, M.; Levicky, D.; Klenovicova, Z. (Společnost pro radioelektronické inženýrství, 2000-12)
    In this paper are presented some results of implementation of digital watermarking methods into image coding based on fractal principles. The paper focuses on two possible approaches of embedding digital watermarks into ...
