In wireless environment, the radio propagation indicates the behavior of the radio waves when they are propagating from transmitter to receiver. These waves are mainly affected by different phenomena such as reflection, diffraction, and scattering. Reflection is a phenomenon; the propagating electromagnetic wave impinges upon an object with bigger dimension compared to the wavelength, for example, wall of building and surface of earth. Diffraction is a phenomenon that occurs when the radio path between the transmitter and receiver is obstructed by a surface with sharp irregularities or small openings and it emerges as a bending of waves around the small obstacles and spreading out of waves through small openings. Scattering is the phenomenon which forces the radiation of propagating wave to deviate from a straight path by more than one local obstacle, like, foliage, street indicating signs, and lamp posts, which are referred to as the scatters. In this paper we will understand impact of these in wireless systems using different fading models. MATLAB is used as a simulation tool.
