Feedback Capacity of Parallel ACGN Channels and Kalman Filter: Power Allocation with Feedback
Song Fang, Quanyan Zhu
In this paper, we relate the feedback capacity of parallel additive colored Gaussian noise (ACGN) channels to a variant of the Kalman filter. By doing so, we obtain lower bounds on…
Relativistic Rocket Control (Relativistic Space-Travel Flight Control): Feedback Control of Relativistic Dynamics Propelled by Ejecting Mass
Song Fang, Quanyan Zhu
In this short note, we investigate the feedback control of relativistic dynamics propelled by mass ejection, modeling, e.g., the relativistic rocket control or the relativistic (sp…
The Spectral-Domain Wasserstein Distance for Elliptical Processes and the Spectral-Domain Gelbrich Bound
Song Fang, Quanyan Zhu
In this short note, we introduce the spectral-domain Wasserstein distance for elliptical stochastic processes in terms of their power spectra. We also introduce the…
Independent Elliptical Distributions Minimize Their Wasserstein Distance from Independent Elliptical Distributions with the Same Density Generator
Song Fang, Quanyan Zhu
This short note is on a property of the Wasserstein distance which indicates that independent elliptical distributions minimize their Wasserstein di…
Independent Gaussian Distributions Minimize the Kullback-Leibler (KL) Divergence from Independent Gaussian Distributions
Song Fang, Quanyan Zhu
This short note is on a property of the Kullback-Leibler (KL) divergence which indicates that independent Gaussian distributions minimize the KL divergence from given independent G…
Fundamental Limits of Controlled Stochastic Dynamical Systems: An Information-Theoretic Approach
Song Fang, Quanyan Zhu
In this paper, we examine the fundamental performance limitations in the control of stochastic dynamical systems; more specifically, we derive generic bounds that h…
