Characterization of LOS signal fading at 6/7 GHz over Assam Valley and its association with tropospheric parameters: An observational study

Abstract

Fading features of microwave signals (6/7 GHz) over Milmilia-Durgasarovar, Maopet-Durgasarovar and Laopani-Habaipur links of Assam Valley are characterized in terms of fade depth and fade duration distributions. The multipath occurrence factors for all the three links are defined after setting up fade distribution equation for each link. The fades over Milmilia-Durgasarovar link only are associated with meteorological and atmospheric variabilities received through two sodar units and a number of sensors placed over this link. The worst month fade depth characteristics over this link are associated with tropospheric ducting.
