一种基于联合加权和截断的毫米波大规模MIMO信道估计
A mmWave Massive MIMO Channel Estimation Based on Joint Weighted and Truncated Nuclear Norm
摘要
Abstract
In this paper,a millimeter-wave massive multiple input multiple output(MIMO)channel estimation algorithm based on joint weighted and truncated nuclear norm is proposed.Aiming at the problem of high training and feedback overhead in millimeter-wave massive MIMO channel estimation,firstly,the channel estimation problem is transformed into a low-rank ma-trix recovery problem by using the sparse antenna angle domain of millimeter-wave channel.An effective and flexible rank func-tion,the joint weighted and truncated kernel norm,is adopted as the relaxation of the nuclear norm,and a new matrix recovery model is constructed for channel estimation.The optimization objective is to minimize the weighted and truncated nuclear norm,and it is solved by an alternating optimization framework.The simulation results show that this method can effectively improve the accuracy of channel estimation and has reliable convergence.关键词
