Abstract :
In this paper the coexistence issue between the UWB systems and Wi-Max/IEEE-802.16 systems has been investigated. The aim is to evaluate the impact that the interference resulting from a realistic UWB hot spot scenario may have on the performance of a Wi-Max/IEEE-802.16 receiver. A mathematical model is developed through which the performance of the interference power produced by the UWB hot spot can be calculated. We use a pulse waveform represented as a generalized form of Gaussian pulse family that can be used in ultra wide band (UWB) impulse radio systems. This pulse waveform ensures that the UWB spectrum mask established by the Federal Communications Commission (FCC) is met. The results against which the UWB interference is assessed are also developed using the specifications of Wi-Max/IEEE-802.16 systems. Several simulations have been done to both validate the analytical results and calculate the UWB interference.
