A method for optimizing spectral re-use between an interferer cellular system and a desirable cellular system is disclosed wherein an acceptable baseband signal to interference ratio (SIR) is determined, and an interference reduction factor (IRF) is determined. The ratio of the SIR to the IRF is determined, and the fourth root of the determined ratio is determined, which fourth root represents the optimal minimum ratio of the distance of a mobile unit from an interferer cellular system to the distance of the mobile unit from a desirable cellular system.
L'invention concerne un procédé d'optimisation de la réutilisation spectrale entre un système cellulaire perturbateur et un système cellulaire voulu et consistant à déterminer un rapport signal de bande de base acceptable/parasites (SIR), et à déterminer un facteur de réduction des parasites (IRF). On détermine le rapport entre SIR et IRF et on détermine la racine quatrième du rapport déterminé, laquelle racine quatrième représente le rapport optimal minimum entre la distance d'une unité mobile la séparant d'un système cellulaire perturbateur et la distance de l'unité mobile d'un système cellulaire recherché.
