Simulation of UHF indoor radio channels for open-plan building environments

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
