Analysis on the Compatibility between UWB and Narrowband Wireless Communication Systems

Abstract

The potential interference of ultra wideband (UWB) on existing narrowband wireless communication systems must be analyzed before it is applied, so the paper uses a method based on the physical layer model to analyze the compatibility of direct-sequence ultra wideband (DS-UWB) and multi-band ultra wideband (MB-UWB) on several narrowband victim systems. Based on the physical layer models of PAM-DS-UWB and PPM-DS-UWB and MB-UWB and these victim systems, depended on the communication condition of victim systems, the power restrictions of UWB are obtained on the operating frequency band of N-CDMA, GSM, WLAN systems. The results can offer a solution for the compatibility between UWB and these victim systems.
