论文摘要
在本文中，我们提出了一种新型的关节混合预言和组合制剂设计，以最大程度地提高单用户正交频施加多路复用毫米波大波系统的平均可实现总和率。我们将模拟预编码器和组合设计的设计作为约束的Tucker2分解，并使用投影的替代最小二乘方法来解决它。这样的公式允许在所有子载体上最大化有效的基带增益的总和，同时抑制了同一子载波中数据流之间的干扰。反过来，数字预编码器和组合仪是根据有效的基带通道的单数值分解获得的。数值模拟结果表明，所提出的方法的表现优于其他现有设计。
In this paper, we propose a novel joint hybrid precoder and combiner design for maximizing the average achievable sum-rate of single-user orthogonal frequency division multiplexing millimeter wave massive MIMO systems. We formulate the analog precoder and combiner design as a constrained Tucker2 decomposition and solve it by using the projected alternate least square method. Such a formulation allows maximizing the sum of the effective baseband gains over all subcarriers, while suppressing the interference among the data streams in the same subcarrier. In turn, the digital precoder and combiner are obtained from the effective baseband channel's singular value decomposition on a per-subcarrier basis. Numerical simulation results show that the proposed method outperforms other existing designs.
