A Selection Method for CoMP clusters in LTE-A System
首发时间:2010-12-22
Abstract:In this paper, we consider a communication system with N base stations, each of which is equipped with M antennas in distributed way, supporting data traffic to K user terminals, each of which is equipped with one antenna. An efficient suboptimum algorithm is proposed for selecting users and antennas to form coordinated transmission/reception (CoMP) groups, which can improve the system performance significantly, especially the performance of cell-edge users. The scheme includes two steps: the selection of antennas groups and the selection of CoMP groups. The first step focuses on clustering antennas with high similarity, while the second step is accomplished by using project matrix which considers both the strength and the orthogonality of receive signals. Simulation results have shown the effectiveness of the proposed scheme.

LTE-A系统中的CoMP分簇算法
摘要:在这篇文章中,我们考虑一个通信系统,这个系统有N个基站,每个基站配置M个分布式天线,支持与K个用户的数据传输,每个用户假设配置一根天线。我们提出了一个有效的算法来选择用户和天线,以形成协作传输/接收组合(CoMP),其可以有效地提升系统性能,特别是边缘用户的性能。这个算法包括两个步骤:选择天线组合和选择CoMP组合。第一个步骤聚焦于以高的相似度选择天线,第二个步骤基于投影矩阵,投影矩阵既考虑了信号的强度又考虑了用户间的正交性。仿真的结果显示了所提算法的性能增益。
