Channel coding with strictly casual colored side-information at transmitter

Abstract

In this paper we study channels where a side-information sequence is available strictly causally at the transmitter, i.e., the channel input at time k may depend on the side-information sequence up to and including time k - 1. This is in contrast to Shannon's channel coding with causal side-information at the transmitter where the channel input at time k may depend on the side-information sequence up to and including time k. We consider side-information sequences with memory and study the Gaussian and modulo-additive channels.
