DISTRIBUTED DYNAMIC CHANNEL ALLOCATION FOR THE EVOLUTION OF TDMA CELLULAR-SYSTEMS

This paper reviews Dynamic Channel Allocation (DCA) in TDMA cellular s ystems. The emphasis is on distributed DCA, which features decentraliz ed control and adaptability to interference. Performance measures are discussed not only from a theoretical viewpoint but also from a practi cal viewpoint. Major techniques to enhance the capacity of cellular sy stems are channel segregation, reuse-partitioning, and transmitter pou er control. In addition to the performance of conventional cellular s ystems, differing performance in microcellular systems and multi-layer cellular systems is also discussed.
