OPTIMAL CHANNEL REUSE IN CELLULAR RADIO SYSTEMS WITH MULTIPLE CORRELATED LOG-NORMAL INTERFERERS

The probability of co-channel interference (PCI) due to multiple corre lated log-normal signals is calculated for cellular radio systems oper ating in Rayleigh fading and log-normal shadowing environment. The eff ects on the PCI of the correlation between the signals, the standard d eviation due to shadowing, the number of interferers, the co-channel p rotection ratio, and the traffic load is investigated. The results are used for analyzing the optimal channel reuse, the cluster size, and t he spectrum efficiency in terms of these parameters.
