%X To solve the complex hardware cost and energy loss issues in millimeter wave massive multiple-input multiple-output (MIMO) communication systems, a lens antenna array beamforming scheme based on an adaptive switch structure is proposed in single-user systems. Compared with the traditional uniform linear array, the proposed scheme can reduce the hardware cost and energy loss of beamforming without significantly degrading the performance. The work further combines the proposed scheme with the block diagonalization zero-forcing algorithm, and the combined hybrid beamforming scheme not only applies to the multi-user communication systems, but also can obtain higher spectrum efficiency.
