Abstract

This paper presents a new Interference Alignment (IA) scheme for K-User Multiple Input Multiple Output (MIMO) Interference Channel (IC) based on two metaheuristics, namely Particle Swarm Optimization (PSO) and Artificial Bee Colony (ABC) Algorithm. Tackling interference is an essential issue in wireless communications to which Interference Alignment (IA) provides a promising solution. However, IA still lacks of explicit and straightforward design procedures. In fact, most of IA procedures aim to minimize a certain Interference Leakage (IL) which measures the effect of the interference on the network, this results in complex optimization tasks involving a large amount of decision variables, together with a problem of convergence of the IA solutions. In this paper the IA optimization is performed using PSO, ABC and their cooperative counterparts, more suitable for large scale optimization. A comparison between the four algorithms is also carried out. The cooperative proposed approaches seem to be promising.
一种基于元启发式的k用户干扰通道干扰对准方法的比较研究
提出了一种基于粒子群算法和人工蜂群算法的k -用户多输入多输出干涉通道干涉对齐(IA)方案。干扰处理是无线通信中的一个重要问题,而干扰对准(IA)提供了一个很有前途的解决方案。然而,IA仍然缺乏明确和直接的设计过程。事实上,大多数IA过程的目标是最小化一定的干扰泄漏(IL),该干扰泄漏度量干扰对网络的影响,这导致涉及大量决策变量的复杂优化任务,以及IA解决方案的收敛问题。本文采用粒子群优化算法、ABC优化算法及其协同优化算法进行IA优化,更适合大规模优化。并对四种算法进行了比较。合作提出的方法似乎很有希望。
