Considering the potential interference of ultrawideband (UWB) on OFDM-based wireless communication systems, this paper studies coexistence issue between UWB with both impulse radio (IR) and multiband (MB) modulation and IEEE802.11n, WiMAX, and LTE downlink systems, using physical layer modeling strategy. According to the physical characteristics of UWB and the victim systems, entire physical layer models are set up. Based on the requirements of bit error rate (BER) and receiver sensitivity of the three victim systems, the emission limits of UWB are respectively obtained. Compared with a method based on interference to noise ratio (I/N) criteria, this method reflects the effect of the actual systems, so the conclusion can provide the reference to formulating the frequency spectrum of UWB within the operating frequency bands of the victim systems. Besides, we also reveal that IR-UWB should be more strictly regulated compared with MB-OFDM because of its time domain characteristic.
