In this paper, a new beamformer design paradigm, named k-regular beamformer, is proposed for massive Multiple-Input Multiple-Output (MIMO) transmission systems to achieve most of the gain inherent to a large antenna array without too much complexity. In the proposed k-regular beamforming scheme, each of multiple data streams for MIMO transmission is multiplied by k complex gains and assigned to k out of available NT transmit antennas, and signals assigned to the same transmit antenna are added and transmitted through the assigned antenna.
