Abstract

Radio propagation models
play a vital role in designing wireless communication systems. The models are
used to estimate the location and number of transmitter stations as well as
predict the transmitter coverage area. Different models have been developed in
literature to predict radio propagation behavior for wireless communication
systems in different operating environments. In this paper, least square
regression analysis was employed to develop a versatile propagation model for
very high frequency broadcasting radio station in vegetation and/or rocky
environment. The developed model was later evaluated by comparing its path loss
prediction result with two existing path loss models in literature. The results
of the comparative performance analyses show that the two existing models
predict highest difference in propagation path loss compared with that from the
developed least square regression model. The developed model when compared with
the estimated value was found to perform favorably well for each route and the
entire coverage area of the transmitter station used as case study. In
addition, the result of the study confirms the findings of other researchers
that there is no single or universal propagation model that exactly fits all
terrains, applications and environments.
