Binary channel capacity

Web(f) Channel capacity is the maximum, over all possible input distributions, of the mu-tual information that the channel establishes between the input and the output. So one lower bound estimate is simply any particular measurement of the mutual information for this channel, such as the above measurement which was 3/8 bits. 6 WebThe channel capacity is a function of only the channel transition probabilities p ( xj / ym) that define the channel. The maximization is over J input variables p ( x1 ), p ( x2 ), …, p ( xJ ), subject to two obvious constraints that each input probability is non-negative and the sum of all input probabilities is 1.
