Distortion-Based Outer-Bounds for Channels with Rate-Limited Feedback

arXiv:2105.03581

Abstract

We present a new technique to obtain outer-bounds on the capacity region of networks with ultra low-rate feedback. We establish a connection between the achievable rates in the forward channel and the minimum distortion that can be attained over the feedback channel.
