A Macrocell Model Based on the Parabolic Diffusion Differential Equation
A method to determine the path loss in macrocells, based on the parabolic diffusion differential equation, disregarding the phase information of the propagating wave, is suggested. The multiple knife-edge approach is applied and only multiple diffracted waves, no reflections, are considered. A non-flat terrain can be handled. The differential equation is solved by using the explicit Forward-Difference method, where the distance between the calculation points can be 5 m in the height direction when the wavelength is only 0.3 metres, which makes the method extremely computer efficient.
