Nonlinear Posterior-Mean Feedback Codes for AWGN Channels
Yingyao Zhou, Natasha Devroye, Milos Zefran +1
Feedback can improve the reliability of communication over additive white Gaussian noise (AWGN) channels. Classical feedback codes are interpretable, or easy to understand, but oft…
Feedback Lunch: Learned Feedback Codes for Secure Communications
Yingyao Zhou, Natasha Devroye, Onur Günlü
We consider reversely-degraded secure-communication channels, for which the secrecy capacity is zero if there is no channel feedback. Specifically, we focus on a seeded modular cod…
Learned codes for broadcast channels with feedback
Yingyao Zhou, Natasha Devroye
We focus on designing error-correcting codes for the symmetric Gaussian broadcast channel with feedback. Feedback not only expands the capacity region of the broadcast channel but…
Higher-order Interpretations of Deepcode, a Learned Feedback Code
Yingyao Zhou, Natasha Devroye, Gyorgy Turan +1
We present an interpretation of Deepcode, a learned feedback code that showcases higher-order error correction relative to an earlier interpretable model. By interpretation, we mea…
