摘要

本文提出了超宽带通信系统的理论地面反射模型。采用具有特定中心频率和带宽的通带矩形脉冲作为传输信号。对超宽带地反射信道采用复形弗里斯传输公式。对接收到的信号进行评估。UWB路径损耗定义为发射和接收信号波形的最大幅度之比。导出了封闭形式的路径损耗表达式。在数据处理中，考虑了1.00、0.10和0.01 m天线高度下地面反射模型的路径损耗和均方根延迟扩展。利用第一菲涅耳区和MMSE断点对路径损耗的双线性回归进行建模。研究了rms时延扩展随天线高度和路径损耗的变化规律。本文讨论了路径损耗和均方根延迟扩展的特性。

Theoretical ground reflection model for UWB communication systems

In this paper, the theoretical ground reflection model for UWB communication systems is proposed. The passband rectangular pulse with specific center frequency and bandwidth is used as the transmitted signal. The complex form Friis' transmission formula is applied for the UWB ground reflection channel. The received signal is evaluated. The UWB path loss is defined as the ratio between the maximum amplitude of the transmitted and received signal waveforms. The closed form path loss expression is derived. For the data processing, the path loss and rms delay spread of the ground reflection model are considered for the 1.00, 0.10 and 0.01 m antenna heights. The double linear regression for the path loss is modeled by using the first Fresnel zone and MMSE break points. The rms delay spread as a function of the antenna height and the path loss is investigated. The characteristics of the path loss and rms delay spread are discussed in the paper.
