Multi-user large-scale MIMO system non-uniform array topological structure and design method

The invention discloses a multi-user large-scale MIMO system non-uniform array topological structure and a design method. The multi-user large-scale MIMO system non-uniform array topological structure comprises a plurality of array elements which are linearly arranged; a first distance is formed between adjacent array elements, and a linear array formed by all the array elements is of a central symmetry structure; the first spacing between the adjacent array elements from the center of the linear array to the two ends is gradually increased; by designing the novel non-uniform linear array of the large-scale MIMO system, the method can be suitable for a multi-user application scene, and meanwhile, the performance of the system is improved. 本发明公开了一种多用户大规模MIMO系统非均匀阵列拓扑结构及设计方法，包括线性排布的若干个阵元；相邻的阵元之间具有第一间距，且由所有阵元组成的线性阵列为中心对称结构；由线性阵列的中心向两端相邻阵元之间的第一间距逐渐增加；本发明通过设计新型的大规模MIMO系统的非均匀线性阵列，可以适用于多用户应用场景，同时提升了系统的性能。
