WebA discrete memoryless channel (DMC) is a channel with an input alphabet AX = { b1, b2, …, bI } and an output alphabet AY = { c1, c2, …, cJ }. At time instant n, the channel maps the input variable Xn into the output variable Yn in a random fashion. The channel is uniquely determined by specifying the conditional probabilities as follows:
