摘要

为了灵活利用毫米波信道中的信道分集和天线阵列的指向性，提出了一种可重构混合波束形成系统。根据信道环境和发射机与接收机之间的相对位置，可以重新配置天线子阵列来调整空间分集和极化分集以及阵列增益。在可重构HBF系统的基础上，提出了一种训练程序，使发射端和接收端根据信道质量和信道特性学习最佳工作模式。与固定HBF系统相比，可重构HBF系统在各种模拟信道条件下的信道容量有3到10 dB的功率增益。

Reconfigurable hybrid beamforming for dual-polarized mmWave MIMO channels

A reconfigurable hybrid beamforming (HBF) system is proposed to flexibly exploit the channel diversities and antenna array directivity in millimeter wave channels. Sub-arrays of antennas can be reconfigured in the proposed HBF system to adjust the spatial and polarization diversities and the array gains according to the channel environments and the relative locations between the transmitter and the receiver. Based on the reconfigurable HBF system, a training procedure is also proposed for the transmitter and the receiver to learn the best operating mode according to channel quality and characteristics. Compared to a fixed HBF system, the reconfigurable HBF system has 3 to 10 dB power gains in channel capacity in various simulated channel conditions.
