A propagation loss prediction model for various types of finite width obstacles using numerical approach

In this paper, propagation loss is predicted by using the Fresnel-Kirchhoff diffraction theory. A novel propagation diffraction loss algorithm is developed in wave propagation environments with various shapes of obstacles. Comparing with the knife-edge model, exact theoretical analysis is performed and diffraction loss is predicted for various types of obstacle. The diffraction loss is simulated using digital terrain map of a region in which actual PCS service is presently operated in Korea.
