摘要

针对干扰对齐的实际应用提出的机会干扰对齐算法（OIA）存在通信资源分配不公平、所需用户基数大等问题。为此，提出一种基于轮询机制的公平高效机会干扰对齐算法。首先确定协作处理簇，并基于轮询机制在主小区中选择信道质量最优的通信用户，然后通过设计次基站的有用信号空间完全消除主小区用户对次基站的干扰，进一步在次小区中以干扰泄露最小化为原则选择通信用户，最后从理论上分析证明了公平性和最小传输块数等性能。仿真结果表明，与原始机会干扰对齐算法相比，所提算法在提升公平性的同时，有效降低干扰泄露和提升系统容量，并且可减少传输块数和实现用户通信接入快速响应。

Abstract

Opportunistic interference alignment (OIA) algorithm was proposed for the practical implementation of interference 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.Furthermore

the users with the minimum interference leakage was selected in the subordinate cells.Finally

the fairness performance 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.
