| 摘 要： |
With the growing relevance of the lower end of the millimeter wave band, a precise characterization of wireless channels in this frequency range is of interest. We conducted an indoor channel measurement campaign at 25.5 GHz in an office floor setting, based on which, we calculated path loss, excess path loss, mean delay and root mean square delay spread. We conclude that the path loss for receiver positions in the same room as the transmitter is adequately described with the free-space path loss, antenna gains, and polarization efficiency. When located in separate rooms, an additional wall loss has to be considered, which remains constant throughout the office floor due to indirect paths with considerable energy. Apart from a higher path loss, propagation effects appear similar to well-known sub-6 GHz channels.
随着毫米波频段下端频率的重要性日益增加，对这一频段无线信道的精确表征变得尤为关键。我们在一个办公室楼层环境中开展了25.5 GHz的室内信道测量实验，并据此计算了路径损耗、超额路径损耗、平均延迟以及均方根延迟扩展。研究结果表明，在与发射器位于同一房间内的接收机位置，其路径损耗可由自由空间路径损耗、天线增益和极化效率充分描述。当设备位于不同房间时，还需考虑额外的墙体损耗，该损耗在整间办公室楼层中保持恒定，因为存在能量较大的间接传播路径。除路径损耗较高外，传播效应与已知的亚6 GHz频段信道基本相似。 |
