A Measurements Based Characterization of Fading in Indoor Millimeter-Wave Distributed Antenna Systems

摘要

In this paper, we empirically investigate the effects of shadowing and multipath fading upon the user equipment (UE) to access point (AP) channels found in indoor distributed antenna systems (DAS) at 60 GHz. Our measurements have considered the signal power simultaneously received at 9 ceiling locations which are likely to be used in future indoor millimeter-wave DAS deployments. During the experiments, a single user imitated making a voice call on a UE, which acted as the transmitter, while walking through an indoor office environment. To characterize the shadowing and multipath fading, we have made use of the lognormal and κ-μ distributions respectively.
