基于毫米波大规模MIMO的共享型阵列混合波束成形算法
Hybrid precoding algorithms base on the fully-connected structure in millimeter wave massive MIMO systems
摘要
Abstract
Considering the high cost and power consumption of the traditional fully-digital beamforming algorithm in milli-meter wave massive multiple input multiple output(MIMO)system,and the poor performance of analog precoding algorithms,a hybrid beamforming algorithm based on the full-connected structure is proposed.Firstly,the phase information is extracted as analog precoding and combining matrix by the singular value decomposition of channel matrix.Then the obtained analog precoding and combining matrix are used together with the original channel matrix as equivalent channel matrix to obtain the corresponding digital precoding and combining matrix by singular value decomposition again.Simulation results demonstrate the proposed hybrid beamforming algorithm can achieve better spectral and energy efficiency than the traditional hybrid beamforming algorithm,while the number of radio frequen-cy chain and data streams are equal.Moreover,the whole singular value decomposition(W-SVD)algorithm is easy to implement in engineering.关键词
