Abstract
Mobile radio communication is the most popular telecommunicational service at the present time. The problem of radio signal attenuation magnitude between base station and mobile station estimation begins when mobile radio communication system signal coverage forecasting. Mobile radio communication system operation actual conditions make it possible to consider radio signal attenuation as function of various random variables.
Attempt to estimate effect of random nature of key parameters of Okumura-Hata & Ibrahim-Parsons propagation models on radio signal attenuation determination accuracy, as applied to Okumura-Hata & Ibrahim-Parsons propagation models, is taken up in paper. Radio signal attenuation variance value is used as measure of accuracy.
Random arguments function linearization principle is used for generation of analytical relations allowing to do research of propagation model parameter random nature effect on radio signal attenuation variance.
Computer simulation was carried on and corresponding schematic linear connections were plotted on the basis of obtained analytic dependences.
Obtained results can be used in design stages of professional mobile radio communication systems and their under-control operation for evaluation and analysis of their functional efficiency characteristics.
