Abstract :
A general information feedback system is defined and formulated in a way broad enough to allow coded or uncoded channels with total dr partial information feedback. Basic theorems governing change in information rate and reliability are derived with full consideration of the transition probabilities of both direct and feedback channels, including message words as well as the confirmation- denial signal.
