Zusammenfassung:The paper puts forward a new link maintenance and compensation model for cognitive UWB radio systems. In this model, the link maintenance is combined with change of modulation method. Performance analysis conducted for this model shows that cognitive UWB supports sub-carriers selection model of band with 528 MHz wide, and the probability of primary users appearance affects goodput through channel processes. The retransmission of last data and the change of modulation method enhance the robustness against primary users interference, as primary users appear, and compensate to data corruption due to primary users interference
