Impact of bandwidth, center frequency and spatial position on the results of ultra- wideband power delay profile measurements and accuracy of predictions

The dependence of power delay profile upon bandwidth (temporal resolution) and center frequency is systematically studied using ultra-wideband measurements. The necessary measurement parameters for wideband channel models construction, validation and construction of precise site-specific propagation prediction models and investigation of propagation mechanisms have been detected. Ray tracing and Finite Integration Technique numerical Maxwell's equation solver accuracy has been estimated and compared on the basis of delay profiles.
