Abstract

Abstract:

An antenna selection scheme of space-time block coding combined with eight-beamforming (STBC-BF) in massive MIMO system was proposed.Transmit symbols were coded by space-time block coder,then the coded symbols were weighted by antenna array form eight-beam.The antenna selection technology was used to select the transmitting antenna and the receiving antenna,traditional decoding method was performed at the receiver.The proposed scheme can not only obtain the space diversity gain and array gain,but also can reduce the computational complexity by reducing the number of the RF links.Simulation results confirm the validity of the proposed scheme.

Key words: massive MIMO, beamforming, space-time block coding, antenna selection
