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.
