Capacity-achieving Feedback Scheme for Gaussian Finite-State Markov Channels with Channel State Information

摘要

In this paper, we propose capacity-achieving communication schemes forGaussian finite-state Markov channels (FSMCs) subject to an average channelinput power constraint, under the assumption that the transmitters can haveaccess to delayed noiseless output feedback as well as instantaneous or delayedchannel state information (CSI). We show that the proposed schemes revealsconnections between feedback communication and feedback control.
