基于轮询机制的公平高效机会干扰对齐算法
Fair and efficient opportunistic interference alignment algorithm based on round-robin scheduling
摘要
Abstract
Opportunistic interference alignment (OIA) algorithm was proposed for the practical implementation of inter-ference alignment (IA). A fair and efficient OIA algorithm was presented for the unfairness in resource allocation and high dependence of tremendous users in the existing OIA algorithms. Firstly, the users with the best channel was selected in the primary cell based on round-robin scheduling after the coordinate cluster was determined. Then, the interference from the primary users was eliminated by skillfully designing the useful signal spaces in the subordinate cells. Further-more, the users with the minimum interference leakage was selected in the subordinate cells. Finally, the fairness perfor-mance was theoretically analyzed. Simulation results show that both the sum-rate and fairness of the proposed algorithm are significantly higher than that of the conventional algorithm with less interference leakage. Besides, the users can achieve a quick access.关键词
