摘要

利用10ns分辨率的宽带信道测深仪测量了一栋6层大学大楼的4个不同楼层在1890兆赫下的脉冲响应。发射机的位置在顶楼,靠近一扇窗外,可以看到附近的校园建筑。测量的功率延迟曲线(pdp)被处理以识别单个射线,在测深仪的分辨率范围内。研究发现,发射机层的RMS时延分布与发射机层的RMS时延分布大不相同,而发射机层的RMS时延分布是发射机层的8倍。给出了每层不同阈值下每个PDP的射线数分布,以及射线在时间和振幅箱中的分布。研究了一种基于测量的统计模型,并用于生成许多pdp的蒙特卡罗模拟。将模拟RMS延迟扩展的累积分布与实测数据进行了比较。

PCS ray characteristics between multiple floors of a concrete building
A wide band channel sounder with 10 ns resolution has been used to measure impulse responses at 1890 MHz on 4 different floors of a 6 storey university building. The transmitter location was on the top floor near an outside window with a view to nearby campus buildings. Measured power delay profiles (PDPs) were processed to identify the individual rays, within the resolution of the sounder. The distribution of RMS delay spreads are found to be quite different for the transmitter floor, compared with the lower floors, where delay spreads are up to 8 times as large. The distributions of the number of rays per PDP for different thresholds are given for each floor, and the distribution of rays in time and amplitude bins is also given. A measurement based statistical model is investigated, and used to generate Monte Carlo simulations of many PDPs. The cumulative distribution of the simulated RMS delay spreads are compared with the measurements.
