Stepian and W~olf [2] gave a characterization for the compression region of distributed correlated sources. Their result is for codes with a decoding probability of error approaching zero as the code length is increased. Of interest in many applications is to find codes for which the probability of error is exactly zero. For this latter case, block codes(More)
