Analysis of system performance of high-capacity mobile radio

Reuse distance and cluster size are evaluated for cellular mobile radio systems. Rayleigh fading, log-normal shadowing, and area mean power inversely proportional to the fourth power of propagation distance are considered using the technique of S.C. Schwartz and Y.S. Yeh (1982) for determining the probability density function of the sum of several log-normal variables to obtain the cochannel interference probabilities. These results are used for analyzing the radio spectrum efficiency, taking call blocking probability into consideration. The cochannel interference probabilities are also calculated using Fenton´s classical method and compared to the values obtained by Schwartz and Yeh´s technique. The results indicate significantly higher probabilities, up to 43% more than the classical method
