Abstract
Orthogonal projection on vector subspaces arises in many applied field s. The common assumption about the orthogonal complementary subspace i s that it is spanned by white noise components. We generalize a previo us perturbation analysis of projection operators to that with a noise field with an arbitrarily structured covariance matrix. The resulting expressions are insightful, and their algebraic power is very useful f or applications.
