Combining Beamforming With Space-time Block Coding in Massive MIMO System

Abstract

An eigen-beamforming combined space-time block coding technique is proposed in massive MIMO systems. At the transmitter, utilize massive MIMO to form orthogonal beams, and then space-time block code is transmitted on these beams. At the receiver, space-time block code is decoded according to traditional decoding algorithm. The proposed technique can obtain diversity gain and beamforming gain simultaneously. Simulation results confirm the validity of the proposed technique.
