Graph theory-based channel modeling is an efficient approach to simulate multipath propagation taking into account the reverberation of electromagnetic waves. In this contribution, without modifying the modeling framework, we proposed a semi-deterministic graph modeling approach by associating the scatterers with realistic environment objects, and by calculating the coefficients of the propagation paths on the base of a proven diffuse scattering theory. An isolated office building scenario is adopted to illustrate the procedure of the proposed method. The performance is thus evaluated by comparing the simulated power-delay-profiles (PDPs) with ray-tracing and real channel measurement data. The results illustrate that the proposed method can accurately predict both the decaying slopes and the diffuse tails of the PDPs.

Abstract
Graph theory-based channel modeling is an efficient approach to simulate multipath propagation taking into account the reverberation of electromagnetic waves. In this contribution, without modifying the modeling framework, we proposed a semi-deterministic graph modeling approach by associating the scatterers with realistic environment objects, and by calculating the coefficients of the propagation paths on the base of a proven diffuse scattering theory. An isolated office building scenario is adopted to illustrate the procedure of the proposed method. The performance is thus evaluated by comparing the simulated power-delay-profiles (PDPs) with ray-tracing and real channel measurement data. The results illustrate that the proposed method can accurately predict both the decaying slopes and the diffuse tails of the PDPs.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
