The ergodic Markov chain (Figure 1) is in steady state at time 0 and its states are given = {a, b, c). Write the equations for as S (1,2,3,4). The corresponding source alphabet is the steady-state probabilities, (g(s)), and solve them. I b: 1/2 a; 1/2 a; 1/2 a: 1 c; 1/2 4 3 19 Figure 1: An ergodic Markov chain.
