Grassmannian line packing
Mar 1, 2016 · WebThen the Grassmannian line packing problem is the problem of finding m points on G ( k, l) that maximizes the minimum distance between the points. In our case, we are trying to pack 2 B points into G ( n ,1). A solution to the Grassmannian line packing problem can be found using PSO. We will maximize the objective function ƒ ( C) = max min d ...

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. Since a Grassmannian code can be isometrically embedded in a hypersphere, the Rankin bound [16] on …
