摘要：
This paper presents a model for propagation loss prediction in indoor mobile communications using parabolic wave equation (PE). The implicit finite differences scheme of the Crank-Nicolson type is applied in order to get the solution of the parabolic equation. The propagation is considered in 15 in the direction paraxial. To validate this model, a measurement campaign was accomplished at a typical five floor building of a university using a frequency of 850 MHz. The loss predicted by this model had a mean error of 4.69 dB and standard deviation of 3.85 dB in relation to the measured data.
