摘要：
This paper presents an iterative beamforming method for the millimeter wave phased array. This method uses the approximate orthogonal property for the different paths in the millimeter-wave channel in the case of a large array, and obtains the path with the largest gain in the millimeter-wave channel by iteratively sending the received signal to the other side. The array responses correspond to the path with the maximum gain are used as a beamforming vector for both the transmitter and receiver. Simulation results show that the spectral efficiency obtained by this method is close to the spectral efficiency obtained by the singular value decomposition(SVD) method and has a performance promotion compared with the existing IEEE802.15.3c method. The proposed method has a fast convergence rate and convergence is generally obtained in 3 iterations. © 2017, The Editorial Board of Journal of Xidian University. All right reserved.
