  • A Simple Signal Shaper for GMSK/GFSK and MSK Modulator Based on Sigma-Delta Look-up Table 

    Svedek, T.; Herceg, M.; Matic, T. (Společnost pro radioelektronické inženýrství, 2009-06)
    Due to wide power spectrums of rectangular data streams, it is important for base-band signals to be heavily band limited before modulation. That can be achieved by pulse shaping of rectangular bits. Some of the most common ...
  • Some Advances in the Circuit Modeling of Extraordinary Optical Transmission 

    Medina, F.; Mesa, F.; Rodriguez-Berral, R. (Společnost pro radioelektronické inženýrství, 2009-06)
    The phenomenon of extraordinary optical transmission (EOT) through electrically small holes perforated on opaque metal screens has been a hot topic in the optics community for more than one decade. This experimentally ...
  • SPICE Model of Memristor with Nonlinear Dopant Drift 

    Biolek, Zdeněk; Biolek, Dalibor; Biolková, Viera (Společnost pro radioelektronické inženýrství, 2009-06)
    A mathematical model of the prototype of memristor, manufactured in 2008 in Hewlett-Packard Labs, is described in the paper. It is shown that the hitherto published approaches to the modeling of boundary conditions need ...
  • Superconductor Microwave Kinetic Inductance Detectors: System Model of the Readout Electronics 

    Alimenti, F.; Ercoli, M.; Palazzari, V.; Roselli, L. (Společnost pro radioelektronické inženýrství, 2009-06)
    This paper deals with the readout electronics needed by superconductor Microwave Kinetic Inductance Detectors (MKIDs). MKIDs are typically implemented in the form of cryogenic-cooled high quality factor microwave resonator. ...
  • Synthetic Aperture Radar - Hardware Development 

    Rosner, V.; Seller, R.; Dudas, L.; Kazi, K.; Miko, G. (Společnost pro radioelektronické inženýrství, 2009-06)
    Experimental real and synthetic aperture radar are developed from the base-band digital unit to the analogue RF parts, based on solid state units, using pulse compression for radar imaging. Proper QPSK code is found for ...
  • Using Digital Filtration for Hurst Parameter Estimation 

    Prochaska, J.; Vargic, R. (Společnost pro radioelektronické inženýrství, 2009-06)
    We present a new method to estimate the Hurst parameter. The method exploits the form of the autocorrelation function for second-order self-similar processes and is based on one-pass digital filtration. We compare the ...
  • UWB System Performance Improvement Using Smart Interference Rejection Filter 

    Dimitrijevic, B.; Milosevic, N.; Nikolic, Z.; Petrovic, P. (Společnost pro radioelektronické inženýrství, 2009-06)
    In this paper we proposed a smart interference rejection filter in TH-PPM UWB system, which improves the system\'s error probability for an order of magnitude in case of high power OFDM interference. The smart filter is ...
  • Wireless Sensor Networks: VAN-Project Perspectives 

    Lakkundi, V.; Kratzig, M. (Společnost pro radioelektronické inženýrství, 2009-06)
    The emergence of wireless sensor networks and their potential for a multitude of novel applications, especially in the industrial automation domain, are noteworthy. This paper presents research and development perspectives ...
