Binary input symmetric channel

WebJun 28, 2009 · Channel polarization is a method of constructing capacity achieving codes for symmetric binary-input discrete memoryless channels (B-DMCs). In the original paper, the construction complexity is exponential in the blocklength. In this paper, a new construction method for arbitrary symmetric binary memoryless channel (B-MC) with … 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:
