This Thesis is to propose and study various channel allocation schemes for the current TDMA and future TDD-CDMA cellular systems to enhance the system capacity. We first propose a channel partitioning idea to use different reuse factors to support multiple services in the TDMA cellular systems. The fixed channel partitioning, called FCP, is analyzed with Markov chain. Both the performances with stationary and mobile users are studied in this Thesis. To further increase the system capacity, a dynamic channel allocation scheme is combined with our proposed channel partitioning idea, called dynamic channel partitioning with interference information (DCP-WI). The main idea behind this DCP-WI scheme is to minimize the effect of assigned channels on the availability of channels for use to the interfering cells.
