Cascaded channels and the equivocation inequality
Metrika, 1978 The variation of the “equivocation” and the average mutual information over cascaded channels is studied, using the generalized information measures (entropies of degree α) and Renyi information measures (entropies of order α). The “equivocation inequality”, which indicates that the equivocation can never decrease as we go further from the input on a ...
