As the complexity of the indoor propagation environment so that the accuracy of analyzing the millimeter wave propagation characteristics are affected. In this paper, ray tracing method is used to analyze the situation of ample area and finite-difference time domain is used to analyze the complex area contains a discontinuity point. The methods are combined to research the indoor millimeter wave. Working frequency was given at 30GHz, source respectively in both indoor and outdoor situation, indoor millimeter propagation characteristics and method of modeling. Simulation results from MATLAB were compared with reference and show that the hybrid method is helpful and accurate for modeling the indoor millimeter. |
