论文摘要
本文考虑了镜头天线阵列辅助毫米波（MMWAVE）多源多输入多输出（MU-MIMO）系统。基站的光束选择矩阵和用户端子的仅相位光束形成器的共同设计，目的是最大化上行链路总和速率。为了处理配制的混合智能优化问题，通过利用加权的最小均方根误差（WMMSE），块坐标下降（BCD）和次要型号（BCD）和较小化 - 临时（MM）技术（MM）技术，开发了基于二元分解（PDD）基于迭代的迭代算法。此外，提出了低复杂的顺序优化（SO）基于少量的速率性能损失的成本。数值结果表明，所提出的方法可以达到比最新方法更高的总和率。
This paper considers a lens antenna array-assisted millimeter wave (mmWave) multiuser multiple-input multiple-output (MU-MIMO) system. The base station's beam selection matrix and user terminals' phase-only beamformers are jointly designed with the aim of maximizing the uplink sum rate. In order to deal with the formulated mixed-integer optimization problem, a penalty dual decomposition (PDD)-based iterative algorithm is developed via capitalizing on the weighted minimum mean square error (WMMSE), block coordinate descent (BCD), and minorization-maximization (MM) techniques. Moreover, a low-complexity sequential optimization (SO)-based algorithm is proposed at the cost of a slight sum rate performance loss. Numerical results demonstrate that the proposed methods can achieve higher sum rates than state-of-the-art methods.
