摘要
为了解决毫米波大规模多输入多输出(MIMO)通信系统中复杂的硬件成本和能量损耗的问题,提出了单用户系统中基于自适应开关结构的透镜天线阵列波束赋形方案。与传统均匀线性阵列相比,该方案在不显著降低性能的前提下,可降低波束赋形的硬件成本和能量损耗。结合块对角化(BD)迫零算法,将所提出的混合波束赋形(HBF)方案推广到多用户通信系统,同样可获得较高的频谱效率。
To solve the complex hardware cost and energy loss issues in millimeter wave massive multipleinput 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.
