研究了基于奇异值分解的发射预编码和接收合并的60 GHz毫米波通信系统，提出了一种多阶段迭代的天线系数训练方法。天线训练分多个阶段陆续进行，每个阶段都有一个基于功率迭代原理的迭代过程。零空间投影被用作内部阶段迭代训练的使能步骤。所提出的训练方法对于射频链的数目相对于发射器和接收器侧的天线数目而言要少得多的系统特别有效。
We study 60 GHz millimeter wave communication systems employing SVD based transmit precoding and receive combining, and propose a multi-stage iterative method in training the antenna coefficients. The antenna training is carried out in multiple stages one after another, while each stage features an iterative process based on the power iteration principle. Null space projection is used as an enabling step for iterative training in inner stages. The proposed training method is especially efficient for systems with a much smaller number of RF chains relative to the number of antennas on both transmitter and receiver sides.
