In this chapter, we review some of the recent developments and prove new results concerning frames and Bessel systems generated by iterations of the form {Ang: g ∈ G, n = 0, 1, 2, …}, where A is a bounded linear operator on a separable complex Hilbert space ℋ and G is a countable set of vectors in (Formula presented). The system of iterations mentioned above was motivated from the so-called dynamical sampling problem. In dynamical sampling, an unknown function f and its future states Anf are coarsely sampled at each time level n, 0 ≤ n < L, where A is an evolution operator that drives the system. The goal is to recover f from these space-time samples.
