Study Of Coexistence Between Uwb And Mobile Communication System

摘要
The objective of the study is to investigate the impact of cumulative interference from multiple UWB systems to the downlink of GSM900, GSM 1800, TD-SCDMA and WCDMA. Since indoor environments are focused on, a three-dimensional geometry for the spatial distribution of the UWB devices is considered. To obtain a realistic scenario, a traffic model describing the transmission activity of the UWB devices is taken into account. In this paper, we use a statistical model, i.e. a probability density function (PDF), describing the cumulative interference from multiple UWB devices. With the 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.
