一种基于遗传算法的OFDMA系统的跨层资源分配
Research on Cross-Layer Resource Allocation for OFDMA System Based on Genetic Algorithm
摘要
Abstract
According to the amount and complexity of computation for cross-layer resource allocation algorithm, an adap- tive cross-layer resource allocation scheme employing Genetic algorithm (GA) in muhiuser OFDMA system is proposed. A better solution to the cross-layer resource allocation satisfying system performances and users' requirements is presented based on the GA characteristics such as parallel processing, comprehensive ability of global search and easy convergence to the optimum. Under the prerequisite of fairness between users met, an improved algorithm is proposed to enhance the availability of frequency spectrum and also shorter the user's average wait delay. The experiment simulation result shows that the method proposed effectively improves cross-layer resource allocation for OFDMA System, and with the increase of Carrier number and the number of users, it has more advantage in complexity of computation.关键词
