  • Efficient Use of Mobile Radio Channels 

    Danek, K. (Společnost pro radioelektronické inženýrství, 1998-09)
    This paper deals with GMSK and 4-Level FSK modulation schemes which are adopted in the land mobile services. The analysis of group delay interaction has been carried out by approximative mathematical reflections. Better ...
  • N-th Order Filters Using Balanced-Output CCII+/- Conveyors 

    Vrba, K.; Cajka, J.; Zeman, V. (Společnost pro radioelektronické inženýrství, 1998-09)
    A novel second-generation current conveyor is defined. A special three-port cell containing the above element is presented. A method for nth-order multifunction circuit realization is described. Two universal networks ...
  • Simple Model of Synchronized System for the Chaotic-Masked Communication 

    Pospisil, J.; Brzobohaty, J.; Kolka, Zdeněk (Společnost pro radioelektronické inženýrství, 1998-09)
    In this paper the simplest form of the compound dynamical system is considered, i.e. the second-order subsystem homogeneously synchronized by the third-order autonomous subsystem where the synchronized block is identical ...
  • Adaptive Beamforming Using Genetic Algorithms 

    Florens, C.; Raida, Zbyněk (Společnost pro radioelektronické inženýrství, 1998-09)
    The presented submission describes how genetic algorithms can be applied to the control of adaptive antennas. The proposed optimization method is easily implementable on one hand, but relatively slowly converging and ...
  • Genetic Optimization of Wire Antennas 

    Goven, E.; Verheyen, L.; Raida, Zbyněk (Společnost pro radioelektronické inženýrství, 1998-09)
    The presented submission describes how genetic algorithms can be applied to the optimization and design of wire antennas. The proposed optimization method is easily programmable and well understandable on one hand, but ...
