Abstract :
Many researchers have studied connections between the problems of feedback control and of communicating over a channel with feedback. We study two such feedback communication schemes, and focus on properties such as phase margin, robustness with respect to unmodeled time delays, and exogenous noise inputs. In particular, we study the impact of unstable poles in the encoder or decoder on these properties, as quantified by the Bode sensitivity integral.
