  • Automatic tunning of Okumura-Hata model on railway communications
    Publication . Beire, Ana Rita; Cota, Nuno; Pinheiro Pita, Helder Jorge; Rodrigues, António
    This paper presents the Genetic Algorithms (GA) as an efficient solution for the Okumura-Hata prediction model tuning on railways communications. A method for modelling the propagation model tuning parameters was presented. The algorithm tuning and validation were based on real networks measurements carried out on four different propagation scenarios and several performance indicators were used. It was shown that the proposed GA is able to produce significant improvements over the original model. The algorithm developed is currently been used on real GSM-R network planning process for an enhanced resources usage.
