Computer simulation of knife-edge based approximate methods for multiple diffraction estimation

Abstract

In the process of a radio network design, the propagation loss estimation is a subject of crucial importance in order to meet the demanded quality-of-service. In terrestrial radio-links, propagation loss is usually caused mostly by free space dispersion and diffraction across the geographical obstacles. Thus, the diffraction phenomenon is an unavoidable issue on courses of radio-communications. Therefore, instead of a professional radio-software, it is convenient for educational purposes to develop a simpler radio-simulation tool, but such that elucidates thoroughly the particular stages of the path-loss estimation. Therefore, a computer simulation of approximate methods concerning multiple-diffraction was developed in MATLAB.
