Binary input symmetric channel
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: WebBinary symmetric channel collapse all in page Syntax ndata = bsc (data,probability) ndata = bsc (data,probability,streamhandle) ndata = bsc (data,probability,seed) [ndata,err] = …

WebThe symmetric capacity I(W) equals the Shannon capacity when W is a symmetric channel, i.e., a channel for which there exists a permutation π of the output alphabet Ysuch that (i) π−1 = π and (ii) W(y 1) = W(π(y) 0) for all y ∈Y. The binary symmetric channel (BSC) and the binary erasure channel (BEC) are examples of symmetric channels ... WebCapacity-Achieving Codes for Symmetric Binary-Input Memoryless Channels Erdal Arıkan, Senior Member, IEEE Abstract—A method is proposed, called channel polarization, to construct code sequences that achieve the symmetric capacity of any given binary-input discrete memoryless channel (B-DMC) .
