摘要

本文介绍了城市购物中心内超高频波传播的宽带信道特性。研究了同电平传播和跨电平传播下宽带测深得到的脉冲响应、多径分量的衰减率以及时延的均方根(RMS)扩展。由于购物中心的封闭结构，多径分量主要是由建筑内部的多次反射产生的，因此它们在两个测试场景中都呈线性衰减。此外，测量得到的延迟扩展值在100ns以内，因此，可用带宽足以用于视频通信。

Wideband channel modeling within a shopping mall in UHF band

Wideband channel characteristics associated with UHF wave propagation within a shopping mall in urban areas are presented in this paper. Impulse responses, decay rate of multipath components as well as the root-mean-square (RMS) delay spread obtained from wideband sounding are studied for both the same level propagation and the inter-level propagation. Due to the enclosed structure of the shopping mall, multipath components are mainly resulted from multiple reflections within the building and therefore they decay linearly for both test scenarios. Moreover, the delay spread value obtained from the measurements is within 100 ns, therefore, the usable bandwidth is sufficient for video communication.
