Feedback Capacity of Gaussian Channels Revisited
Ather Gattami
In this paper, we revisit the problem of finding the average capacity of the Gaussian feedback channel. First, we consider the problem of finding the average capacity of the analog…
Team Decision Problems with Convex Quadratic Constraints
Ather Gattami
In this paper, we consider linear quadratic team problems with an arbitrary number of quadratic constraints in both stochastic and deterministic settings. The team consists of play…
Optimal Communication of States of Dynamical Systems over Gaussian Channels with Noisy Feedback: The Scalar Case
Ather Gattami
We consider the problem of communicating the state of a dynamical system via a Shannon Gaussian channel. The receiver, which acts as both a decoder and estimator, observes the nois…
Optimal Data and Training Symbol Ratio for Communication over Uncertain Channels
Ather Gattami
We consider the problem of determining the power ratio between the training symbols and data symbols in order to maximize the channel capacity for transmission over uncertain chann…
Time Localization and Capacity of Faster-Than-Nyquist Signaling
Ather Gattami, Emil Ringh, Johan Karlsson
In this paper, we consider communication over the bandwidth limited analog white Gaussian noise channel using non-orthogonal pulses. In particular, we consider non-orthogonal trans…
Primal robustness and semidefinite cones
Seungil You, Ather Gattami, John C. Doyle
This paper reformulates and streamlines the core tools of robust stability and performance for LTI systems using now-standard methods in convex optimization. In particular, robustn…
