Frequency–angle two-dimensional reflection coefficient modeling based on terahertz channel measurement
太赫兹信道传播特性对太赫兹通信系统的设计、评估和优化至关重要。此外, 反射在信道传播中起着重要作用。本文基于大量的信道测量工作, 对太赫兹通道的反射系数进行研究。首先, 建立从220 GHz到320 GHz的太赫兹信道测深**台, 入射角范围从10°到80°。根据实测的传播损耗, 分别计算玻璃、瓷砖、木板、石膏板和铝合金五种建筑材料的频率和入射角的反射系数。研究发现, 由于缺乏与太赫兹相关的参数, 导致非金属材料的菲...

A study of uplink and downlink channel spatial characteristics in an urban micro scenario at 28 GHz
This paper presents an empirical study of the uplink and downlink azimuth angle of arrival (AoA) in an urban micro (UMi) scenario at 28 GHz. At present, most UMi measurements are conducted in the downlink and ...
