  • Impact of Ultra Wide Band (UWB) on Macrocell Downlink of DCS-1800 and GSM-900 Systems 

    Taha-Ahmed, B.; Calvo-Ramon, M.; Haro-Ariet, L. D. (Společnost pro radioelektronické inženýrství, 2005-04)
    The effect of UWB interference on the DCS-1800 and GSM-900 downlink is studied for different UWB power density. For high UWB power density (-70 dBm/MHz), the effect of UWB signals is very high when the distance between UWB ...
  • Intelligent FDSS Overlay on GSM System (Uplink Analysis) 

    Taha-Ahmed, B.; Calvo-Ramon, M.; Haro-Ariet, L. D. (Společnost pro radioelektronické inženýrství, 2005-04)
    The overlay of an intelligent frequency diversity spread spectrum system (FDSS) on the (GSM) system is studied. The uplink capacity of both systems is given using a model of 36 hexagonal macrocells. Performance of GSM and ...
