[Easy-to-understand communication] Channel capacity and information rate-distortion function

Information rate-distortion function : Find the maximum compression of the source (ie maximize H(X|Y)), and make the required information transmission rate R after encoding as small as possible (ie minimize I(X;Y))

Channel capacity : the maximum value of average mutual information, that is, the maximum capacity of the channel to transmit information
