空间积分法分析UWB对移动通信设备的合成干扰

Interference of UWB devices on mobile system by using space integral methodology

针对大量室内超宽带(UWB)无线通信设备同时处于活动状态时的情况,提出一种空间积分法模型用于计算UWB干扰的合成效应,并结合受干扰系统的性能衰减模型,研究UWB设备对移动无线通信系统设备的合成干扰。将PHS、GSM和TD-SCDMA三种移动通信系统的手持机,分别作为UWB设备环绕中的受干扰接收器,依据所建立的模型,分析它们在不同链路预算衰减情况下,所能承受的最大UWB合成干扰、UWB设备密度以及UWB设备和受干扰接收器之间的最小距离。

According to the scenario of co-activities of many indoor UWB wireless radio devices,space integral methodology model is used to calculate synthesize issues of UWB EMI,and then with performance attenuation model of victim system,synthesize interference of many UWB devices on other mobile system is studied.PHS,GSM and TD-SCDMA handset is used as victim receiver,to calculate the maximum UWB synthesize interference,density of UWB devices and least distance between UWB device and victim receiver.
