This paper presents the verification of indoor propagation channel simulations based on an intelligent ray launching algorithm (IRLA) in the Ka-band of the millimeter-wave (mmWave) spectrum in various indoor environments, including a classroom, an office, and a corridor, by radio channel measurements. Power delay profiles (PDPs), path loss, and root-mean-square (RMS) delay spreads were obtained from both the simulation results and the measurement results. Moreover, parameters of two site-general path loss models, the close-in free space reference distance path loss model and the floating-intercept path loss model, were estimated based on the measured and simulated path loss. The comparison between the simulation results and the measurement results indicates that the IRLA-based simulation can accurately describe the main characteristics of the indoor propagation channel in the Ka-band.

Ka波段室内环境智能射线发射算法的验证

本文介绍了基于智能射线发射算法 (IRLA) 在毫米波 (mmWave) 频谱的 Ka 波段在各种室内环境（包括教室、办公室和走廊）中进行室内传播信道模拟的验证，通过无线电信道测量。功率延迟分布 (PDP)、路径损耗和均方根 (RMS) 延迟扩展均从仿真结果和测量结果中获得。此外，基于测量和模拟的路径损耗估计了两个站点通用路径损耗模型的参数，即近距离自由空间参考距离路径损耗模型和浮动拦截路径损耗模型。
