Near-Earth Propagation Loss Prediction in Open Rural Environment using Hybrid Empirical Neural Model

New hybrid empirical neural (HEN) model for prediction EM field level of wireless communication transmitter in frequency range 150-1500 MHz is presented in this paper. Previous empirical Okumura-Hata model, which has been very often used, does not consider all influences of environment that signal goes throughout. Therefore, the results obtained by this model can disagree with the measured results. Considering Okumura-Hata model as approximate empirical knowledge holder and connecting it with the artificial neural network, in this paper we will realize the HEN model whose estimated results are more closed to measured results than Okumura-Hata results.
