Abstract

This work analyzes the potential interference impact on Geostationary Earth Orbit (GEO) satellites stemming from Multipoint Video Distribution System (MVDS) transmissions, specifically examining side lobe radiation within Lebanon. Through simulations and analysis of antenna emission patterns, the study measures how varying MVDS power outputs affect the carrier-to-noise (C/N) ratio at the satellite receiver. Results reveal a significant impairment of signal quality, showing the C/N falling to -2.3 dB with an MVDS power level of 0 dBW under current system parameters. To counter this interference, a potential two-phase mitigation strategy is presented and its effectiveness considered. The study contributes to improving the prospects for compatible operation between MVDS and GEO satellite services within the Ku-band, considering the Lebanese context.
