MATHEMATICAL MODELING OF RADIOSIGNALLOSSESINMOUNTAINOUS REGIONS: DIFFRACTION, TERRAIN, ANDATMOSPHERIC ABSORPTION

Abstract

Modern radio communication systems, including digital television, areplacing increasingly high demands on the reliability and stability of radiochannelsin a complex physical-geographical environment. It is particularlychallenginginmountainous areas where the propagation of radio waves occurs under conditionsof sharply expressed heterogeneity of the relief, significant height variations,shielding, and numerous obstacles that cause significant energylossesandinstability of the received signal.
