Abstract :
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 dn where 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
