摘要

大规模多输入多输出(MIMO)的波束形成和到达方向(DOA)估计在第五代(5G)蜂窝网络中起着重要作用。针对5G gndeb中的MIMO天线系统，对几种现有的DOA和波束形成算法进行了验证。提出了一种基于32元等间距线性阵列的递推最小二乘多尔夫切比雪夫(RLS-DC)非盲自适应波束形成算法。副瓣电平从-14 dB抑制到-30 dB，同时获得从-60º到+60º的转向区域。

An Investigation of Adaptive Digital Beamforming Antenna for gNodeB 5G

Beamforming and the direction of arrival (DOA) estimation for the massive multi-input multi-output (MIMO) play a significant role in the fifth-generation (5G) cellular networks. Several existing DOA and beamforming algorithms are validated for the MIMO antenna system in 5G gNodeB. The proposed non-blind adaptive beamforming algorithm using Recursive least squares Dolph Chebyshev (RLS-DC) with Uniformly spaced Linear Array (ULA) of 32 elements is presented in this paper. The sidelobe level is suppressed from -14 dB to -30 dB while steering area from -60º to +60º is obtained.
