中文摘要:

块 diagonalization (BD ) 是在连接下面消除内部用户的干扰在的一种有效 precoding 技术多重输入多重产量(MIMO ) 系统。与 BD 用于多用户 MIMO 系统的用户选择策略在这篇文章被调查。提高多用户 MIMO 系统的能力,相等的能力最大值(ECM ) 用户选择策略与低计算复杂性被建议。认为两个是隧道关联和隧道的因素调节,建议策略能选择一组用户当作最大化全部的产量。模拟结果显示为各种各样的隧道条件,那建议 ECM 策略与传统的用户选择策略相比获得更好的表演,并且作为彻底的搜索完成近最佳的产量。

英文摘要:

Block diagonalization (BD) is an efficient precoding technique that eliminates inter-user interference in downlink multiple-input multiple-output (MIMO) systems. User selection strategies applied to multiuser MIMO systems with BD are investigated in this article. To enhance the capacity of multiuser MIMO systems, an equivalent capacity maximum (ECM) user selection strategy is proposed with low computational complexity. Considering both the factors of channel correlations and channel conditions, the proposed strategy can select a group of users to serve for maximizing the total throughput. Simulation results indicate that, for various channel conditions, proposed ECM strategy gains a better performance compared with traditional user selection strategies, and achieves a near optimal throughput as the exhaustive search.
