  • Robust GPS Satellite Signal Acquisition Using Lifting Wavelet Transform 

    Djebouri, D.; Djebbari, A.; Djebbouri, M. (Společnost pro radioelektronické inženýrství, 2006-04)
    A novel GPS satellite signal acquisition scheme that utilizes lifting wavelet to improve acquisition performance is proposed. Acquisition in GPS system is used to calculate the code phase (or shift) and find the pseudo-range, ...
  • Motion Compensated Video Compression with 3D Wavelet Transform and SPIHT 

    Enyedi, B.; Konyha, L.; Fazekas, K. (Společnost pro radioelektronické inženýrství, 2006-04)
    The following paper introduces a low bitrate video coding method on the basis of 3D motion compensated wavelet transform and SPIHT algorithm. In contrast to the conventional algorithms applying motion compensation and ...
  • High Resolution of the ECG Signal by Polynomial Approximation 

    Jurko, S.; Rozinaj, G. (Společnost pro radioelektronické inženýrství, 2006-04)
    Averaging techniques as temporal averaging and space averaging have been successfully used in many applications for attenuating interference [6], [7], [8], [9], [10]. In this paper we introduce interference removing of the ...
  • Lattice RLS for Nonstationary Signal Processing 

    Djigan, V. I. (Společnost pro radioelektronické inženýrství, 2006-04)
    The paper presents the modification of lattice RLS adaptive filtering algorithms for the case of nonstationary signal processing. The modification includes the using of sliding window and dynamic regularization in the ...
  • FPGA Based Test Module for Error Bit Evaluation in Serial Links 

    Kolouch, J. (Společnost pro radioelektronické inženýrství, 2006-04)
    A test module for serial links is described. In the link transmitter, one module generates pseudorandom pulse signal that is transmitted by the link. Second module located in the link receiver generates the same signal and ...
  • Analog Group Delay Equalizers Design Based on Evolutionary Algorithm 

    Ziska, P.; Laipert, M. (Společnost pro radioelektronické inženýrství, 2006-04)
    This paper deals with a design method of the analog all-pass filter designated for equalization of the group delay frequency response of the analog filter. This method is based on usage of evolutionary algorithm, the ...
  • X-Band PLL Synthesizer 

    Vagner, P.; Kutin, P. (Společnost pro radioelektronické inženýrství, 2006-04)
    This paper deals with design and realization of a PLL synthesizer for the microwave X−band. The synthesizer is intended for use as a local oscillator in a K−band downconverter. The design goal was to achieve very low phase ...
  • UWB Propagation through Walls 

    Schejbal, V.; Bezousek, P.; Cermak, D.; Nemec, Z.; Fiser, O.; Hajek, M. (Společnost pro radioelektronické inženýrství, 2006-04)
    The propagation of ultra wide band (UWB) signals through walls is analyzed. For this propagation studies, it is necessary to consider not only propagation at a single frequency but in the whole band. The UWB radar output ...
  • Simple Chaotic Oscillator: From Mathematical Model to Practical Experiment 

    Petrzela, J.; Kolka, Zdeněk; Hanus, S. (Společnost pro radioelektronické inženýrství, 2006-04)
    This paper shows the circuitry implementation and practical verification of the autonomous nonlinear oscillator. Since it is described by a single third-order differential equation, its state variables can be considered ...
