A Study on the Analysis of UWB Interference to WiMAX and Mitigation Method of Transmit Power Control

This paper presents the analysis of the potential ultra-wideband(UWB) interference to WiMAX at 3.5 GHz bands and the mitigation method using transmit power control(TPC) of UWB system. UWB interference effect is evaluated with WiMax`s outage probability over UWB density when multiple UWB systems and single WiMAX receiver distribute in unit area of 1, When UWB distribution density is 20 and the dynamic range of TPC is 30 dB, UWB interference effect with TPC is decreased by 42 % rather than that without mitigation scheme. Finally, we describe that the proposed TPC is an effective method to mitigate UWB interference to WiMAX.
