Abstract :
Shannon´s zero-error channel capacities COF, CO with and without noiseless feedback are generalized to list decoding: the receiver lists L messages, erring if the correct one is not listed. The corresponding capacities COF(L), CO(L) are nondecreasing in L. For an I-letter input alphabet, COF(L) attains its maximum at L=I-1. A lower bound to CO(L ) approaches that maximum as L increases
