Investigation of propagation mechanisms in a typical cellular communication system

This paper investigates the different propagation mechanisms and their effects on path loss and delay spreads in a typical cellular system by using a three-dimensional ray-tracing propagation model to provide site-specific field predictions. The deterministic ray-tracing model enables the identification of the dominant propagation paths contributing to the total received field strength and a quantitative analysis of the propagation mechanisms involved. Comparisons between theoretical results and measurements have shown good agreement for power delay profiles, root-mean-square delay spreads and signal path loss
