Abstract :
For certain fortunate choices of source/channel pairs, all sophisticated coding is in vain: for them, a code of block length one is sufficient to achieve optimal performance. Is the set of “fortunate choices” larger if we allow for codes of block length M? For a certain class of discrete memoryless source/channel pairs, we can prove that the answer is negative as long as M is finite
