The potential interference of Ultra wideband (UWB) sufficiently consider the physical structure for UWB and on existing narrowband wireless communication systems must victim system, so this paper uses a method based on the be analyzed before it is applied, so the paper uses a method physical layer model [4] to analyze the interference causing based on the physical layer model to analyze the compatibility of by UWB on N-CDMA, GSM, WLAN systems, and obtain the direct-sequence ultra wideband (DS-UWB) and multi-band ultra .' ' . t wideband (MB-UWB) on several narrowband victim systems. p erimisouWB, frerore,theintrfeenc so mn Based on the physical layer models of PAM-DS-UWB and PPM-UWB devIces surround one narrowband system also Si DS-UWB and MB-UWB and these victim systems, depended on analyzed. In this paper, N-CDMA system is significantly the communication condition of victim systems, the power considered, the others only list the results of analysis. In the restrictions of UWB are obtained on the operating frequency section IV, these results are compared with the values using band of N-CDMA, GSM, WLAN systems. The results can offer a the link budget method based on I/N criteria. solution for the compatibility between UWB and these victim systems. II. METHODOLOGY
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
