This comprehensive treatment of network information theory and its applications provides
the first unified coverage of both classical and recent results. With an approach that …

In this paper, we introduce a fundamental principle for optimal communication over general
memoryless channels in the presence of noiseless feedback, termed posterior matching …

Sequential rate-distortion (SRD) theory provides a framework for studying the fundamental
trade-off between data-rate and data-quality in real-time communication systems. In this …

We consider a discrete-time linear-quadratic-Gaussian (LQG) control problem, in which
Massey's directed information from the observed output of the plant to the control input is …

Feedback control systems are designed to achieve desirable objectives under physical
constraints and adversary conditions. Fundamental control limitations address the intrinsic …

This work develops a new method for estimating and optimizing the directed information rate
between two jointly stationary and ergodic stochastic processes. Building upon recent …

Next generation cyber-physical systems challenge the standard assumption of classical
control theory that communication can be performed instantaneously, reliably, and with …

Despite numerous bounds and partial results, the feedback capacity of the stationary
nonwhite Gaussian additive noise channel has been open, even for the simplest cases such …

This paper studies networked control systems closed over noiseless digital channels. We
focus on noisy linear time-invariant (LTI) plants with stationary Gaussian disturbances …

A coding theorem is proved for a class of stationary channels with feedback in which the
output Y n= f (X nm n, Z nm n) is the function of the current and past m symbols from the …
