Abstract: This paper studies the relation between the two subspaces spanned by a frame sequence and its general perturbed version in Hilbert spaces by using the properties of orthogonal projection and the properties of dual frames. This paper also studies the stability of fusion frame systems under general perturbation of the local frame vectors. Our results generalize and improve the remarkable results which had been obtained by Casazza, Kutyniok and Li.

Key words: Frame sequence, Perturbation, Local frame, Fusion frame systems, Stability
