Abstract
Let \(\bigl \{W(\cdot |\cdot ,s):s\in \mathcal{S}\bigr \}\) be a family of stochastic matrices with common input and output alphabets. A compound channel (CC) (introduced by it) is defined as a family of channels \(W^n(\cdot |\cdot ,s)\), where for all \(x^n\in \mathcal {X}^n\), \(y^n\in \mathcal {Y}^n\), \(s\in \mathcal{S}\) \(W^n(y^n|x^n,s)=\prod \limits _{t=1}^nW(y_t|x_t,s)\).
