Abstract
This paper deals with the Interference between Fixed Satellite Service (FSS) and IMT-Advanced (4G) for Malaysian environment. The study initiated within detailed calculations of the current and 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. Thereafter, FSS axis received gain and radiation pattern had been covered. Furthermore, Site shielding, isolation, off-Axis, In-Band and Out of band have been discussed in several scenarios. Calculations, analysis and simulation have been done by using Matlab software. Consequently, extracted conclusions had highlighted the subsistent situation and proposal for future work.
