Abstract We provide a practical implementation of the rubber method of Ahlswede et al.for binary channels. The idea is to create the “skeleton” sequence therein via an arithmetic decoder designed for a particular k-th order Markov chain. For the stochastic binary symmetric channel, we show that the scheme is nearly optimal in a strong sense for certain parameters. A byproduct of the analysis is a strict enlargement of the rates for which the sphere-packing bound is known to be achievable with feedback for this channel.
