Probability of signal-to-interference ratio in mobile cellular systems
Ervin B. Zentner, Sonja Zentner Pilinsky · 2006
The probability functions of a sum of co-channel interference signals in a mobile cellular network are analyzed under the assumption that the signal variations follow the Rayleigh distribution and the mean power decreases as dnwhere n = -3.5. On numerical examples if is shown that the probability function of the sum of interfering signal can be approximated with a Rayleigh distribution with the mean roughly equal to the mean of the strongest interference signal. A comparison of efficiency between two cellular systems is carried out based on these facts
