Compatibility Analysis for Wireless Systems in VHF/UHF Bands with Geographic Information

Topic: Mobility
Format: PDF
By using radio propagation predictions of Rec. ITU-R P.1546 combined with geographic information, formulations for field calculation and interference analysis are presented in the VHF and UHF bands. To illustrate some computational results for the given system parameters, virtual and real geographic data are taken into account. Performance and protection ratio including the net filter discrimination are reviewed for the fixed wireless system interfered with the radar operated at the co-channel frequency as well as frequency offset. Interference effect of the victim receiver has been also examined by varying radar beam direction over azimuth and elevation angles. The developed methodology can be actually applied to evaluate interoperability between wireless systems under the net-centric warfare environment.
