摘要
根据FCC模板和ETSI草案模板限制,分析了室内均匀分布于三维空间的UWB设备对GSM系统下行链路的合成干扰。运用多维积分法模型计算出GSM系统在不同的链路预算衰减情况下所能承受的最大UWB设备密度以及UWB设备与受干扰GSM终端设备间的最小距离。分析结果表明,ETSI模板限制更能满足两系统间电磁兼容的要求,而FCC模板限制能否保证两系统间的电磁兼容有待进一步研究。
According to current FCC and ETSI regulations, cumulative interference from multiple UWB devices to the downlink of GSM cellular system in indoor environments has been studied. Suppose that multiple UWB devices are uniformly distributed throughout the threedimensional space, the maximum UWB device density and the minimum distance between UWB device and GSM terminal were calculated. The analysis results showed that ETSI regulation is better than FCC regulation.
