  • Rain Scattering and Co-ordinate Distance Calculation 

    Hajny, M. (Společnost pro radioelektronické inženýrství, 1998-12)
    Calculations of scattered field on the rain objects are based on using of Multiple MultiPole (MMP) numerical method. Both bi-static scattering function and bi-static scattering cross section are calculated in the plane ...
  • An Ischemic Disease Classification of Lower Limbs 

    Rozman, J.; Zona, M.; Peroutik, J. (Společnost pro radioelektronické inženýrství, 1998-12)
    An ischemic disease of lower limbs is a manifestation of general arteriosclerosis. Its early noninvasive diagnostic is possible using the approach of the Doppler measurement of the blood flow in the vessels with following ...
  • An Approach to 2D Wavelet Transform and Its Use for Image Compression 

    Vargic, R. (Společnost pro radioelektronické inženýrství, 1998-12)
    In this paper is constructed a new type of two-dimensional wavelet transform. Construction is based on lifting scheme. We transform 1D wavelets with symmetrical factorisation to their 2D counterparts. Comparison to existing ...
  • ARC Filters with Diamond Transistors and Buffers 

    Dostal, T. (Společnost pro radioelektronické inženýrství, 1998-12)
    Active RC first and second order filters using diamond transistors (voltage controlled current sources) and voltage diamond buffers (voltage controlled voltage sources) are given in this paper. Circuits are simulated and ...
  • Generalized Sampling Theorem for Bandpass Signals 

    Prokes, A. (Společnost pro radioelektronické inženýrství, 1998-12)
    Bandpass time-continuos signals are shown being able to be uniquely expressed in terms of the samples gi(nTv) of the impulse responses gi(t) of m linear time-invariant systems with input f(t) sampled at 1/m Nyquist rate. ...
  • Differential GMSK Receivers with Phase Control for Narrowband Radio Communications 

    Mahdavi, A.; Gordon, D.; Riley, N. (Společnost pro radioelektronické inženýrství, 1998-12)
    An implementation method for differential Gaussian Minimum Shift Keying receivers with Phase Control is presented. It is shown that in such receivers the effect' of InterSymbol Interference (ISI) on the signal, caused by ...
  • A PC Controlled Filter 

    Pagel, S.; Fontan, F. P.; Van Looy, M. (Společnost pro radioelektronické inženýrství, 1998-12)
    In this paper we present a switched capacitor filter design using the SC22324 1C, which is fitted with an E2PROM. It contains four digitally programmable switched-capacitor filter sections, in order to obtain different ...
  • Speech Segmentation Using Bayesian Autoregressive Changepoint Detector 

    Cmejla, R.; Sovka, Pavel (Společnost pro radioelektronické inženýrství, 1998-12)
    This submission is devoted to the study of the Bayesian autoregressive changepoint detector (BCD) and its use for speech segmentation. Results of the detector application to autoregressive signals as well as to real speech ...
  • Study of 2-input 2-output Blind Signal Separation by Output Decorrelation 

    Machuca, E.; Sovka, Pavel; Davidek, V. (Společnost pro radioelektronické inženýrství, 1998-12)
    The simulations and experiments representing the initial study of the output decorrelation approach to blind signal separation are presented in this paper. The definition of performance indexes for the evaluation and ...
