Abstract
Orthogonal Frequency Division Multiple Access (OFDMA) is a potential multiple access technology in current mobile networks. Frequency reuse is frequently employed to boost a communication system's capacity, but it also increases user interference. In cellular systems, frequency reuse necessitates the employment of several strategies to reduce interference. Different channel allocation techniques present resource utilization and quality of service tradeoffs in different methods. Under the framework of Fractional Frequency Reuse (FFR), several channel allocation algorithms were studied for network capacity, including integer frequency reuse (IFR), integer frequency reuse (IFR) and Forward-Looking game (FLG). The network is simulated using MATLAB to compare the network capacity of various combination schemes with different input parameters and to study the variation pattern of network capacity with input parameters. The results reveal that the signal-to-noise ratio, user allocation rate, average number of users, and number of cells are all affecting aspects of network capacity, and FLG + SWF performs similarly to SWF + FLG while outperforming other combination methods. This paper includes the FFR method to explore the network capacity of various combination methods, which is useful for determining the ideal input parameters and further rules for different algorithm combination strategies in different networks.
