| Popis: | For fifth generation mobile communication systems (5G) utilization of the band from 6 to 100 GHz is investigated to increase the system capacity, because it is relatively easy to ensure the wide bandwidth in these frequencies. Considering the capital investment involved in establishing 5G service areas, utilizing non-line-of-sight (NLOS) environments for service areas is desirable. Moreover, since beamforming will be utilized to compensate large path loss in higher frequencies, it is important to understand the relationship between the multipath and the city structure in a NLOS environment in which compensating for path loss is more important than LOS environment. In this report, we investigate the relationship between the multipath and the city structure around intersections based on delay profiles measured using a horn antenna in a NLOS street cell environment. The results clarify that diffraction waves from building corners and reflected waves from building walls that exist along the street on which a mobile station is deployed are dominant paths. |
