Grassmannian line packing
WebB. Grassmannian codes An (N,δ) code in GC n,p is a finite subset of N points in the Grassmannian with (pairwise) minimum distance among the elements δ. A packing is a code that maximizes the minimum distance for a given cardinality.

WebOct 11, 2024 · In this paper, to tackle the effect of the PC, we propose a block-diagonal Grassmannian line packing (GLP) approach, in which the specific sequences for different cells are first designed based on the GLP, and then are block-diagonally extended to form the SP matrices for the users in different cells. To also alleviate the effect of DI on the ...
