摘要
针对大量超宽带(UWB)无线通信设备共处一室的情况,从三维空间并考虑UWB设备活动性的统计角度得出UWB设备的干扰统计模型。结合受干扰系统的性能衰减模型研究多个UWB设备对分别处于其环绕之中的PHS,GSM和TD-SCDMA 3种移动通信系统手持机在不同链路预算衰减情况下,分析它们所能承受的最大UWB合成干扰、UWB设备密度以及UWB设备和受干扰接收机之间的最小距离。
The objective of the study is to investigate the impact of cumulative interference from multiple UWB systems ro the downlink of PHS, GSM-900, GSM-1800, TD-SCDMA. Since indoor environments are considered a three-dimensional geometry for the spatial distribution of the UWB devices is assumed. To obtain a realistic scenario a model describing the transmission activity of the UWB devices is taken into account. The outcome of this study is a statistical model, i.e. a probability density function （PDF）. With this model, the maximum interference from multiple UWB devices, the maximum acceptable UWB-device density, the minimum distance between UWB devices and receiver are derived in different link budget degradation.
