Empirical / Ray-tracing Hybrid Approach for COST 231 Unknown Building Layouts

Uncertainty in structure geometry is a fundamental limitation of ray-tracing methods of simulating urban propagation, exacerbated by performing analysis which pass into buildings of unknown configuration. Empirical models provide an alternative, but do not incorporate the full impact of the neighboring urban structures. Presented is a hybrid approach using ray-tracing methods to arrive within the building and applying empirically derived loss factors to incorporate the effect of unknown interior layouts. This approach is compared with a more typical empirical implementation to demonstrate the benefits of hybridization.
