【 摘 要 】

This paper presents the radio propagation measurement, simulation, and analytical results in the 41-GHz millimeter-wave band for non-line-of-sight scenarios in a confined in-building corridor environment. High gain directional antennas are used at both the transmitter and receiver to realize long-distance transmission. Directional channel characteristics of the 41-GHz band, including the path loss model, the root-mean-square delay spread, the multipath statistics, the small scale fading characteristics, the power delay profile, and the power levels received from different antenna directions at different locations, are analyzed in detail. Moreover, in the investigation of the path loss models, we employ ray tracing simulations to extend the path loss model to a more general form so that the structural characteristics of the corridor, such as the length of the line-of-sight section and the corridor corner angle, are considered as modeling parameters. The effects of different transmit/receive antenna locations on the path loss model are also investigated. The combined effects of the highly directional antennas and the confined corridor environment on the wireless channel characteristics are analyzed in detail.
