Industrial indoor multipath propagation — A physical-statistical approach

摘要

In this work, a novel physical-statistical technique for simulating the industrial indoor multipath propagation is proposed. The indoor propagation environment is described by a cubic volume in a rectangular coordinate system. The clustering behavior of the multipath components is modeled by defining circular spaces within the propagation environment containing uniformly distributed scatterers. Each scatter within a cluster is modeled as a finite lossy dielectric cylinder with a given size, orientation, and material type. A step-by-step method for simulating the industrial indoor multipath channel impulse response is provided. The power-delay-profiles (PDP) obtained by the developed method is consistent with the Saleh-Valenzuela model and with reported indoor measurement results. The advantages of the proposed technique is that large scenarios might be simulated more effectively than using purely physical methods and could also be more accurate than empirical models as it takes into account the material type, size, orientation and density of the scatterers.
