Study on the Emission Limits of UWB Based on the Entire Physical Layer Model Method

Aiming at the effect of ultra wideband (UWB) system for the potential victim systems on UWB operating frequency band, using the entire physical layer model method, this paper studies the interference of direct-sequence ultra wideband (DS-UWB) and multi-band ultra wideband (MB-UWB) on these victim systems. Depended on the physical characteristics of UWB and these victim systems, the entire physical layer models are set up. Based on the requirement of bit error rate (BER) and sensitivity of receiver of these victim systems, the emission limits of UWB are obtained on the operating frequency band of these victim systems, The conclusion not only can provide the reference to constitute the frequency spectrum strategy of UWB, but also can offer a solution to the coexistence between UWB and these victim systems.
