Large scale survey for radio propagation in developing machine learning model for path losses in communication systems

Scientific African, 2023
Several orthodox approaches, such as empirical methods and deterministic methods, had earlier been used for the prediction of path loss in wireless communication systems. These approaches are either inefficient or complex.
