摘      要：In this paper,the impact of the interference from multiple ultra wideband（UWB） transmitters to a 3rd-generation（3G） terminal is evaluated under UWB emission power limit regulations of federal communications commission（FCC）,european telecommunications standards institute（ETSI） and Japan respectively.A three-dimensional interference model is presented where a discrete spatial distribution of UWB transmitters is *** is assumed that a mobile terminal and a large number of UWB devices exist in one room simultaneously.A parameter which characterizes the link budget degradation at the victim receiver is defined to measure the UWB interference to 3G *** maximum acceptable density of UWB transmitters and the minimum acceptable distance between UWB transmitters and the 3G terminal are analyzed under different link budget *** simulation results demonstrate that the performance of time division-synchronous code division multiple access（TD-SCDMA） is the best,the one of code division multiple access 2000（CDMA2000） is the worst and the one of wideband code division multiple access（WCDMA） lies between them in presence of UWB interference.
