Abstract:
We address the problem of correcting a single error in an arbitrary discrete memoryless channel with error-free instantaneous feedback. For the case of a one-time feedback, we
propose a method for constructing optimal transmission strategies. The obtained result allows
us to prove that for a binary channel, two feedbacks are sufficient to transmit the same number
of messages as in the case of complete feedback. We also apply the developed techniques to
a binary asymmetric channel to construct transmission strategies for small lengths.
Keywords:
coding with feedback, symmetric channel, asymmetric channel, Hamming bound, linear programming problem.
