Abstract
Field strength data from 13 single-knife-edge diffraction propagation paths were collected over the Indian subcontinent. The suitability of different prediction methods is compared. It is concluded that in urban regions, urban loss should be added to the predicted path loss to explain the observed loss, whereas in the rural/semiurban areas, Epstein-Peterson, Deygout, and CCIR methods predict path losses, which are in close agreement with the observed values
