Computation of expected interference between FSS and imt-advanced for fixed and mobile users in deferent malaysian environments. Maltepe Üniversitesi. s. 235.9.78605E+12https://hdl.handle.net/20.500.12415/2373The impact of single and aggregates cases of IMT-Advanced (4G) systems on Fixed Satellite Services (FSS) earth station (ES) was conducted in this research paper for deferent Malaysian environments. The study initiated within detailed calculations of the most useful formulas for path loss effect and clutter loss by using the existing parameters of FSS and the most expected parameters for the IMT-Advanced. Site shielding, isolation, off-Axis, and in-band have been concluded, analyzed and simulated using Matlab software for several scenarios. Numerical formulas to calculate the power of the interference signal received at the FSS ES when IMT-Advanced base stations (BS) are operated is presented. Simulation results indicate that the proposed mitigation scheme is highly efficient in terms of reducing the separation distance as well as robust against DOE estimation errors. The study also used the propagation model of Rec. ITU-R P.525 to see the effect of terrain profile on the separation distance of the two systems for frequency sharing. Finally, the frequency sharing results are analyzed in the co-channel with respect to minimum separation distance, possible FSS elevation angle, and direction of FSS-ES (DOE).enCC0 1.0 Universalinfo:eu-repo/semantics/openAccessConference Object236235
