  • BER and SIR Based Hybrid Link Algorithms Performance in Mobile Radio Channel 

    Wieser, V.; Psenak, V. (Společnost pro radioelektronické inženýrství, 2005-12)
    In the next generation of mobile communication networks (B3G) the using of effective handling of radio resources is supposed (channels, power and transmission rate) with simultaneous delivery of required services, in which ...
  • Mutual Interference Models for CDMA Mobile Communication Networks 

    Wieser, V.; Hrudkay, K. (Společnost pro radioelektronické inženýrství, 2002-12)
    Nowadays we are witnesses of a huge development one of the most progressive communication technology - mobile networks. The main problem in these networks is an elimination of the mutual interference, which, mainly in ...
  • Performance of Advanced Hybrid Link Adaptation Algorithms in Mobile Radio Channel 

    Wieser, V.; Psenak, V. (Společnost pro radioelektronické inženýrství, 2008-09)
    The fast power adaptation is essential for WCDMA based mobile radio networks, as 3G UMTS. Although the first version of UMTS has been released in 1999 (Release 99) evolution was not finished yet. Quality of Service (QoS) ...
  • Performance of Predictor Based Link Adaptation Algorithms 

    Wieser, V.; Psenak, V. (Společnost pro radioelektronické inženýrství, 2009-12)
    The presented paper deals with the link adaptation algorithms in mobile radio access networks based on Wideband Code Division Multiple Access (WCDMA). The mobile radio channel has a significant impact on the transmitted ...
  • Power Control Imperfection in CDMA Systems with Adaptive Antennas 

    Hrudkay, K.; Wieser, V. (Společnost pro radioelektronické inženýrství, 2002-12)
    This paper deals with a simulation of cellular CDMA system using base station adaptive antennas. The model assumes two tiers area, four types of antennas, lognormal shadowing corresponding to three types of environments ...
