本文介绍了一种开放式建筑物内UHF室内无线信道的软件信道模拟器。该模拟器是基于宽带统计模型的个别多径分量的幅度和延迟。该模拟器创建紧密间隔的信道脉冲响应的视线（LOS）和阻塞（OBS）的地形。仿真中考虑了收发距离的影响以及各个多径分量幅度随时间和空间的相关性。该模拟器已经被扩展以通过合成多径分量的相位来产生小距离上的窄带衰落。多径功率延迟分布，RMS延迟扩展分布，和窄带衰落分布的模拟器准确地描绘典型的无线电信道在各种开放式建筑环境。<<ETX>>
A software channel simulator for UHF indoor radio channels in open-plan buildings is introduced. The simulator is based on wideband statistical models of individual multipath component amplitudes and delays. The simulator creates closely spaced channel impulse responses for both line-of-sight (LOS) and obstructed (OBS) topographies. The effects of transmitter-receiver (T-R) distance and the correlation of individual multipath component amplitudes over time and space are incorporated in the simulation. the simulator has been extended to yield narrowband fading over small distances by synthesizing the phases of multipath components. Multipath power delay profiles, RMS delay spread distributions, and narrowband fading distributions produced by the simulator accurately portray typical radio channels in a variety of open-plan building environments.<<ETX>>
