Abstract

The ability to predict the Frequency Modulation (FM) signals over a predetermined coverage area is of paramount importance for planning of wireless networks. Existing empirical propagation Path-Loss (PL) model such as Egli, Okumura-Hata, COST-231 Hat and Hata-Davidson have not been investigated for predicting the FM signals in Osun state, Nigeria, due to localization of the models. In this paper, applicability of the existing models is investigated on the FM frequency to select the most appropriate model for optimization. The investigation is carried out by measuring the received signal power to determine the PL values for two selected FM stations through a drive test. The drive test equipment consisting of Agilent spectrum analyzer, computer system and global positioning system that used to determine the applicability of the models to the FM stations. The COST 231-Hata model that give the closest values to the measured ones is then optimized using genetic algorithm. The performances of the selected PL models and optimized model are evaluated using PL, root mean square error and mean absolute error. The results obtained showed that the optimized COST 231-Hata model is the appropriate model for predicting the FM stations in the study area.
