*f*from inner products $$\langle f , \varphi _{n} \rangle $$ ⟨ f , φ n ⟩ . We consider the problem of how additive noise affects the reconstruction under the assumption that $$\{ \varphi _{n} \}$$ { φ n } form a stationary sequence. Unlike other reconstruction methods, such as frame reconstructions,...
