An adaptive multi-resolution algorithm for 2D simulations of indoor propagation

In this paper a multi-resolution FDPF approach has been proposed. More precisely, a new nonregular pyramidal structure which fits the particular arrangement of the indoor environment has been presented. The use of a full-space discrete simulator instead of classical ray-tracing techniques is a challenge due to the inherent high computation requests. However, we demonstrate that the use of a multi-resolution approach allows one to perform some calculus in a pre-processing phase, independently of source locations.
