Let's say we have the following wireless communication system with obstacles located as drawn in this picture
Solving this using Bullington method is straight-forward, only obstacles that fall into first Fresnel zone are taken into account, then, for those who DO fall into first Fresnel zone, we determine it's height, and then, using some formulas, we find diffraction loss.
However, i need to do this using another approach, called Epstein-Peterson method. Since im not that familiar with that approach and i tried to google it and i failed to find any examples that are understandable to me, i'd like to hear from someone who is familiar with this method. Any help appreciated!
NOTE: I am not quite sure if this is the right place for this type of questions, however, since there's no such thing as telecom engineering stack exchange, i decided to ask here.
