  • 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 ...
  • Efficient Use of Mobile Radio Channels II 

    Danek, K. (Společnost pro radioelektronické inženýrství, 2000-06)
    This paper is focused on the use of the mobile radio channels, comparing the efficiency of analog double-conversion superheterodyne receiver and software radio. The task of mutually comparing both technologies is made ...
  • 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 ...
  • 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 ...
