Abstract:
The approach presented herein provides a simple and accurate propagation model for indoor environments. The model is able to generate point sources with joint angle-delay-power characteristics that are sensitive to the macrostructure of the site's floorplan geometry. This is achieved in two stages. First, the floorplan geometry is reduced to an essential set of features using an automated routine based on computational geometry. Then an algorithmic set of propagation rules founded on finite difference time domain and ray tracing simulations are applied to the reduced geometry to reconstruct propagation paths. Simulation results are presented and compared with recent data from a measurement campaign for the same scenario. The model is seen to accurately capture the macrostructure characteristics of the channel including angle spread, delay spread, temporal clustering, angular clustering, and power profile.
