A novel and efficient deterministic approach to
model radio wave propagation channels in complex indoor
environments improving prediction accuracy is proposed. This
technique combines a 3-D Ray Launching algorithm based on
Geometrical Optics with a Diffusion Equation method based on
the equation of transfer. A comparison between the Geometrical
Optics only approach and the new method considering the
Diffusion Equation has been presented for studying indoor radio
wave propagation. The Geometrical Optics-Diffusion Equation
method achieves better agreement with measurements, while
resulting in high computational efficiency, with approximately
40% savings in simulation time. [--]
