Assume that a discrete channel is defined by the state transition matrix

Determine an equivalent block diagonal Markov model having two good states and two bad states. (Note: This channel model represents another test case presented by Sivaprakasam and Shanmugan [6].
Compare the result with that found by Sivaprakasam and Shanmugan.
