Method for Determination of Propagation Model Coefficients Using Linear Regression and 3 Dimension Ray Tracing

摘要

The present invention relates to a method for calculating propagation model coefficients using linear regression and three-dimensional ray tracing.;To this end, the present invention checks the geographic information data of the area to design the wireless network, and using the three-dimensional ray tracing method, to identify the propagation path transmitted from the transmitting antenna of the wireless network, to receive one or more reception Graph the relationship by calculating the amount of propagation loss at the point and the distance between the receiving point and the transmitting antenna, and using the linear regression method to calculate the relationship between the distance and the amount of propagation loss, and then estimate the propagation model coefficients from the relationship. In addition, the present invention provides a method for calculating a propagation model coefficient for predicting an accurate radio wave required for the design of a wireless network.;According to the above configuration, it is possible to calculate the propagation model coefficients using the linear regression method and the three-dimensional ray tracing method only by knowing the geographic information data, so that accurate network analysis can be performed in the design of the wireless network. Network design can be easily performed.;Linear regression, ray tracing, radio network, propagation model coefficients, propagation prediction
