Abstract

Shannon [38] introduced the first analysis of discrete memoryless channels with side information, in the form of varying channel states from a finite set, causally known to the encoder. He proved that this channel is equivalent (in terms of capacity) to a usual memoryless channel that has the same output alphabet and an expanded input alphabet with no side information. Accordingly, each letter of the new input alphabet is generated as a mapping from the set of states into the input alphabet of the original channel.
