Favorable propagation (FP) for massive multiple-input multiple-output (MIMO) systems with uniform and non-uniform linear arrays is considered. A gap in the existing FP studies of identified, which related to existence grating lobes array pattern results condition being violated, even under distinct angles arrival. novel analysis design are proposed cancel restore favorable all This consistent p...

Due to its excellent performance and high design freedom, the lattice structure has shown capabilities considerable potential in aerospace other fields. Inspired by bamboo structure, a cell configuration namely BCC4IZ is designed alternative layout obtained. Then, modeling method for non-uniform structures proposed. Four designs of landing footpad with different kinds cells are developed. A ser...
