Motivated by control problems over wireless fading channels, the mean square stabilization of a linear system over a time-varying finite rate feedback link is studied. Process and observation disturbances are allowed to occur over an unbounded support. Necessary and sufficient conditions to stabilize the system are derived, and their implications are discussed. Proof techniques rely on both information theoretic and control theoretic tools.
