In land mobile systems, the reuse distance between Co-channel base stations is traditionally determined according to acceptable level of interference at the victim mobile station. This is a “deterministic” methodology in which probability of interference is not considered. Hence, the reuse distance calculation is based on worst case scenarios. Clearly, such systems do not frequently operate in such scenarios, hence leading to inefficient use of spectrum.
