摘要:With the help of radio propagation prediction of Rec. ITU-R P.1546 combined with geographic information, we present a comprehensive formulation of interference analysis based on the minimum coupling loss, which is applicable to the frequency coordination for wireless systems, and also suggest the S-I plane and local coordinate system for obtaining antenna gains resulting from azimuth and elevation angles between the victim receiver and the interferer. To check the presented methodology, the map with the land-sea mixed zone was taken for the given geographical area of ][60802km., and computational results were achieved for radar and fixed wireless system in terms of field strength, path profile, BER performance, and protection ratio with maximum allowable interference level. In addition interference power s of the victim receiver have been evaluated as a function of frequency dependent rejection, azimuth and elevation angles of the interferer. The developed methodology of interference analysis in the VHF and UHF bands can be actually applied to assess compatibility of wireless systems regardless of frequency bands as well as applications
