Prediction of Mobile Radio Wave Propagation in Complex Topography

Author: Qaysar S.Mahdi

Abstract:  This work studies the prediction of the mobile radio performance and examines the two dimensional mobile radio coverage in case of free space propagation and interference wave propagation for different types of polarization, different types of reflection coefficients, different types of reflecting rough and smooth surfaces. The results show that free space range is less than the interference range but the interference coverage has the lobe structure which causes nulls in the coverage and no signal will be detected in these nulls. Also the results show that the range for the free space propagation is the same for vertical and horizontal polarization but it is greater than the range in case of using circular polarization. The detection range is decreased because of the increasing of the transmitting frequency due to the atmospheric attenuation. This research is widely applicable for V/UHF wireless radio systems, Also it is new approach in simulating and modeling the mobile radio wave propagation and it is very useful as a research and training simulator for the undergraduate and postgraduate students.
