摘　　要：研究了多个UWB(超宽带)设备对其他窄带接收机所产生的累积干扰。分析了干扰分布场景,从接收机抗干扰特性的角度,基于接收机灵敏度这一衡量接收机性能的重要指标,结合"干扰温度"模型,针对UWB设备对UMTS(通用移动通信系统)系统的干扰,采用符合相关系统规范要求的参数进行了仿真。仿真结果表明,FCC(美国联邦通信委员会)频谱掩码不能够满足多个UWB设备与UMTS系统的共存要求,同时UWB设备的分布以及频谱掩码对于累积干扰有很大影响。The cumulate interference of multiple UWB devices with other narrowband receivers is studied and the distributed interference scene is analyzed. From the view-point of the receiver＇s anti-interference characteristics, based on the important index of the receiver＇ s sensitivity which serves to measure the receiver＇ s performance, and according to the model of ‘interference temperature＇ , simulations using the parameters to meet related system requirements are carried out with regard to the interference of UWB devices with UMTS system. As indicated by simulation results, the FCC＇ s spectral mask cannot meet the coexistence requirements of the multiple UWB devices and the UMTS system, while the distribution of UWB devices and the spectral mask have a great influence on the cumulate interference.
