METHOD FOR PROPAGATION LOSS PREDICTION COMBINING HATA MODEL AND RAY TRACING METHOD

摘要

1. This invention belongs to the art described in the claims ; The present invention, which combines the ray tracing model and Hata propagation path loss estimation method and a program-readable recording medium recorded with a computer for realizing the method thing of. ; 2. SUMMARY OF THE INVENTION The attempt to resolve ; The present invention, macro cell proven efficacy in experimental models of Hata model with micro cells in accurate predictions of theoretical models capable of integrating beam propagation method by combining tracking provide a model to estimate more accurately the propagation path loss of the two-layer (macrocell and microcell) adjacent areas (areas where conflicts of propagation path loss estimate), that combines the ray tracing propagation path loss estimation model and Hata provided with a recording medium readable by the computer the method in which a program for realizing that its purpose is to. ; 3. Solution subject matter of the invention ; The present invention, according to Hata model and beam propagation path loss estimation method that combines the tracking method, using a ray tracing method in the first predetermined coverage around the base station first propagation path loss estimation step of calculating a first propagation path loss; A second propagation path loss estimation step of calculating a second propagation path loss by Hata model within the coverage of the second predetermined center to the base station; Parameter determining step of determining a weight coefficient according to the analysis, and the radius of the radius of the analysis, whether the conflicting station estimates the propagation path loss. '; And the calculated first and second propagation path loss value and the third propagation path loss estimate to calculate a third propagation path loss from the analysis on the basis of the determined radius of the weight coefficient, the propagation path loss is estimated to be in conflict areas " including step. ; 4. An important use of the invention ; The present invention used to fight the system and network design.
