论文摘要
本文提出了用于毫米波（MMWAVE）多输入多输出（MIMO）回程系统的混合波束形成设计，配备了在发射机和接收基站的双极化天线的均匀平面阵列（UPAS）。所提出的波束形成设计将考虑到双极化UPA结构的近乎临时求解优化问题。基于优化问题的解决方案，本文表明，可以从最佳的单极化边界器共享相同的最优性中生成最佳的双极化光束器。作为特定示例，对于优化标准，分别考虑了内部产品的平方误差和大小。为了优化提议的波束形式，需要部分通道信息，还提出了低架空飞行员序列的使用来找出所需的信息。仿真结果验证了所得的波束形式的增益最大（带有平方误差标准）或最高平均增益（具有内部产品标准的幅度），其覆盖区域具有双极化天线的UPA。
This paper proposes hybrid beamforming designs for millimeter-wave (mmWave) multiple-input multiple-output (MIMO) backhaul systems equipped with uniform planar arrays (UPAs) of dual-polarization antennas at both the transmit and receive base stations. The proposed beamforming designs are to near-optimally solve optimization problems taking the dual-polarization UPA structure into account. Based on the solutions of optimization problems, this paper shows it is possible to generate the optimal dual-polarization beamformer from the optimal single-polarization beamformer sharing the same optimality. As specific examples, squared error and magnitude of inner product are considered respectively for optimization criteria. To optimize proposed beamformers, partial channel information is needed, and the use of low overhead pilot sequences is also proposed to figure out the required information. Simulation results verify that the resulting beamformers have the most uniform gain (with the squared error criterion) or the highest average gain (with the magnitude of inner product criterion) in the covering region with the UPA of dual-polarization antennas.
