The utility of limited feedback for coding over an individua l sequence of DMCs is investigated. This study complements recent results showing how limited or noi sy feedback can boost the reliability of communication. A strategy with fixed input distribution P is given that asymptotically achieves rates arbitrarily close to the mutual information induced by P and the state-averaged channel. When the capacity achieving input distribution is the same over all c hannel states, this achieves rates… CONTINUE READING
