摘要

本文对娱乐公园中典型信息站场景的UWB信道测量数据进行了时间色散分析。测量在3.1-5.3 GHz频带内进行，并在不同视距(LOS)场景下进行。在传统的用时延扩展分析超宽带信道时间色散特性的方法之外，本文还对超宽带信道的平稳性进行了分析。平稳性结果表明，航道统计数据的变化程度明显，在某些航道上偏差较大。这种平稳性分析的相关性是通过对平稳性概念解释的一些实际见解来预测的。

Measurement and time dispersion analysis of UWB channels for Infostation application in an outdoor recreation park

In this paper the time dispersive analysis of a set of data obtained from the UWB channel measurement of an environment typical of the Infostation scenario in a recreation park is presented. The measurements were carried out in the frequency band of 3.1-5.3 GHz in various line-of-sight (LOS) scenarios. Beyond the conventional approach of analyzing the time dispersion characteristic of the UWB channel by mean of delay spread, this paper includes the analysis of the UWB channel stationarity. Stationarity results show that the degree of variation in the channel statistics is clearly observable with large deviations at some channels. The relevance of such stationarity analysis is projected with some practical insight into the interpretation of the stationarity concept.
