Consider a binary erasure channel, in which the input X ∼ Bernoulli ? (1 ?, 3) and the output Y ∈ {0, e, 1} where the symbol e denotes an erasure event (e appears when the channel is too “bad”). The conditional distribution of Y given X is as follows: pY |X (0|0) = 0.9, pY |X (e|0) = 0.1, pY |X (1|1) = 0.8, pY |X (e|1) = 0.2. Given that an erased symbol has been observed, i.e., Y...
