RADIO CHANNEL PREDICTION BASED ON STREET MAPS USING MODULAR ENVIRONMENTAL ELEMENTS

摘要

A method of modeling predicted values, at a selected point, of radio fields originating from a source in a geographic area including a plurality of streets and a plurality of buildings includes determining a first path from the source to the selected point, the first path including a first segment, and predicting a value, at the selected point, of a radio field originating from the source by modeling the first segment as a first waveguide, and at least one of (1) generating a first radio field coupling equation by coupling the first waveguide with a second waveguide, the second waveguide being a model of a second segment, the second segment being included in the first path, and (2) generating a second radio field coupling equation by coupling the first waveguide with an indoor model for modeling radio fields traveling through a building or outer wall.

1. A method of modeling predicted values of radio fields originating from a source in a geographic area including a plurality of streets and a plurality of buildings, the method comprising:
selecting a point within the geographic area; determining a first path from the source to the selected point, the first path including a first segment corresponding to a first street from among the plurality of streets, the first segment running along the first street; and predicting a value, at the selected point, of a radio field originating from the source, wherein predicting the value of the radio field at the selected point includes,
modeling the first segment as a first waveguide,at least one of
generating a first radio field coupling equation by coupling the first waveguide with a second waveguide, the second waveguide being a model of a second segment, the second segment being included in the first path and running along a second street from among the plurality of streets, andgenerating a second radio field coupling equation by coupling the first waveguide with an indoor model for modeling radio fields traveling through one or more of the plurality of buildings or an outer wall, andpredicting the value of the radio field at the selected point based on at least one of the first and second radio field coupling equations.
