【摘要】 本文对基于3.5GHz频段的无线宽带移动通信系统的多径测量技术进行了研究,提出了一种多径测量方法,并根据该方法,搭建了一套测量系统。通过实地外场的测量,获得了外场信道功率延迟分布和抽头延迟线模型,并在此基础上分析了平均功率延迟分布、接受电平的累计分布和概率分布,提取功率延迟分布的抽头延迟线模型。更多还原

【Abstract】 This paper studies different multipath radio channel measurement techniques and proposes a technical solution for multipath channel measuring and modeling for broadband wireless mobile communication systems.This proposed solution is implemented to measure a multipath channel at 3.5GHz frequency band in the real field and obtains the power delay profiles.By analyzing the measurement data,the average power delay profile,the cumulative distribution function and probability density function of received signal level are derived.Finally,a tapped delay line model based on power-delay distribution is given and discussed.更多还原
