Abstract :
In this paper the effect of aggregate interference produced by a group of ultra wideband (UWB) transmitters using direct sequence technology on a Wi-Max/IEEE-802.16 based system is investigated. Various simulations with different parameters like victim receiver bandwidth, carrier frequency, activity factor and the number of users are performed to measure the produced interference. Finally these measured values are compared to the maximum tolerable interference levels specified for Wi-Max systems to assess if UWB system will create problems for the operation of Wi-Max/IEEE 802.16 based system. It is demonstrated that in a realistic hot spot scenario, the interference produced by the UWB system will fall below the threshold values and this system will not harm the operation of the Wi-Max receiver.
