一种3D-MIMO动态自适应码本设计方法
Novel Dynamic and Adaptive Method to Design Codebook for 3D-MIMO
摘要
Abstract
Full dimension massive multiple-input multiple-output(MIMO) system can significantly improve spatial resolution,reduce inference and improve power efficiency.When uniform planar array is configured at the base station and path loss is taken into consideration,this paper proposes a nonsymmetrical,dynamic and adaptive codebook design method based on the Kroneeker product codebook.The method requires that the amplitude of the beam coverage area is not less than δ dB attenuation of that of the beam center.Starting from the edge of the coverage of the base station,the proposed method calculates each code word and puts it into codebook,thereby leading to larger coverage until the whole area is covered.Compared with the conventional DFT codebook,characteristics of the proposed codebook are analyzed.The new codebook can effectively partition the area into several circular areas and improve the density of beams at the edge of the cell.Finally,the size of the proposed code is analyzed in terms of δ dB attenuation and number of antennas.关键词
