Abstract
We have no satisfactory capacity formula for most channels with finite states.
Here, we consider some interesting examples of finite state channels,
such as Gilbert-Elliot channel, trapdoor channel, etc., to reveal special
characters of problems and difficulties to determine the capacities.
Meanwhile, we give a simple expression of the capacity formula for
Gilbert-Elliot channel by using a hidden Markov source for the optimal
input process. This idea should be extended to other finite state channels.
