The transition probabilities of a communication channel are given by the following channel matrix $\begin{pmatrix} 0.4 & 0.6\\ 0.6 & 0.4 \end{pmatrix}$ Assume that the source probabilities are $P(x_1) = 0.2$, $P(x_2) = 0.8$. (a) Determine the output symbol probabilities $P(y_1)$ and $P(y_2)$. (2 marks) (b) Calculate $H(x)$, $H(x|y)$ and $I(x;y)$. (8 marks) (c) Calculate the channel capacity. (2 marks) (d) Determine the channel input probabilities (i.e., $P(x_1)$, $P(x_2)$) that achieve the channel capacity. (2 marks)
