An efficient hybrid beamforming for uplink transmissions of 60GHz millimeter-wave communications

Abstract

In this investigation, a promising hybrid beamforming technology for the uplink transmissions of the emerging 60 GHz millimeter-wave system is proposed, in order to effectively compromise the performance and implementation complexity. The beam switching based on the predefined beam codebook, is applied at the transmitter; while a step-wise refinement-based beam switching technology and further improved recursive least squares algorithm are used at the access point receiver. The simulation further validates the effectiveness of this presented hybrid beam forming algorithm, and the results show that our new scheme can significantly enhance the SINR performance of the received signal in access point. © 2012 Springer Science+Business.
