Higher-dimensional coherence of subspaces
Stephen D. Howard, Songsri Sirianunpiboon, Douglas Cochran
Abstract
A measure of the smallest angle between two p-dimensional subspaces of a higher-dimensional vector space is introduced. This p-coherence is seen to generalize standard measures of coherence, and its relationship to canonical correlation is noted. The use of p-coherence as a test statistic for the presence of a common p-dimensional signal subspace in data collected by two arrays of K > p sensors is proposed.
