  • Communication Subsystems for Emerging Wireless Technologies 

    Raida, Zbyněk; Kolka, Zdeněk; Marsalek, R.; Petrzela, J.; Prokes, A.; Sebesta, J.; Gotthans, T.; Hrubos, Z.; Kincl, Z.; Klozar, L.; Povalac, A.; Sotner, R.; Kadlec, P. (Společnost pro radioelektronické inženýrství, 2012-12)
    The paper describes a multi-disciplinary design of modern communication systems. The design starts with the analysis of a system in order to define requirements on its individual components. The design exploits proper ...
  • Correctness of Velocity Evaluation of System Using Spatial Filter 

    Prokes, A. (Společnost pro radioelektronické inženýrství, 2002-09)
    In this paper, a velocity measurement method using the spatial filter is presented. Luminous emitance of the surface passing through the moving spatial filter and optical set is projected to the active area of photo-detector. ...
  • 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. ...
  • Implementation of Industrial Narrow Band Communication System into SDR Concept 

    Bobula, M.; Danek, K.; Prokes, A. (Společnost pro radioelektronické inženýrství, 2008-12)
    The rapid expansion of the digital signal processing has penetrated recently into a sphere of high performance industrial narrow band communication systems which had been for long years dominated by the traditional analog ...
  • Influence of Temperature Variation on Optical Receiver Sensitivity and its Compensation 

    Prokes, A. (Společnost pro radioelektronické inženýrství, 2007-09)
    In the paper, the influence of temperature variation on the sensitivity of an avalanche-photodiode-based optical receiver applied in the free space optical communication link is discussed. Communication systems of this ...
  • Modeling of Atmospheric Turbulence Effect on Terrestrial FSO Link 

    Prokes, A. (Společnost pro radioelektronické inženýrství, 2009-04)
    Atmospheric turbulence results in many effects causing fluctuation in the received optical power. Terrestrial laser beam communication is affected above all by scintillations. The paper deals with modeling the influence ...
  • Simplified Frame and Symbol Synchronization for 4–CPFSK with h=0.25 

    Bobula, M.; Danek, K.; Prokes, A. (Společnost pro radioelektronické inženýrství, 2008-06)
    This paper examines the problem of rapid frame and symbol synchronization techniques intended particularly for constant envelope modulation formats M–CPFSK with modulation index h=1/M which are used in strictly bandwidth ...
  • The Transimpedance Amplifier Noise Optimization for the Atmospheric Optical Link Receiver 

    Prokes, A. (Společnost pro radioelektronické inženýrství, 1996-12)
    This paper deals with design of wideband low-noise preamplifier of atmospheric optical link receiver. Sources of noise and the noise models for the PIN photodiode coupled to a transimpedance amplifier are described here. ...
