Abstract :
This paper presents a new model based on the geometrical-optical theory and the uniform theory of diffraction (GO-UTD) for predicting the characteristic of RF propagation in rectangular tunnel. It transforms three-dimensional (3D) propagation model of radio signal in tunnel to two-dimensional (2D) propagation model, which could be easily tackled. Simulation results compared with another prediction model (wireless insite) show that this model can accurately predict the narrow band propagation characteristic of radio signal in rectangular tunnel. Moreover, it reduces the computational complexity greatly and improves the efficiency of prediction.
