WebMay 31, 2013 · I am working through Cover, Thomas "Elements of Information Theory" and want to try and implement a simple example of a binary symmetric channel. That is to say, I can specify a message "1001", an encoding "11000011" (basically repeat each bit twice), a channel law: p(y x), and I'd like to see my posterior at the receiver update. WebA. Consider a binary symmetric communication channel, whose input source is the alphabet X = {0,1} with probabilities {0.5,0.5}; whose output alphabet is Y = {0,1}; and whose channel matrix is
WebA quick google search for "capacity of binary asymmetric channel" gives a few papers stating a closed form solution (for example this paper of Stefan Moser).I've never personally seen a derivation of this, so following on from Dinesh's very nice answer we can attempt to find the capacity exactly using calculus. WebTo count the number of possible sets C, we use that C is symmetric, meaning, if ( b, c) ∈ C then also ( c, b) ∈ C. Now, let [ A] 2 be the collection of subsets of A of size 2. Note [ A] 2 consists of subsets rather than ordered pairs. Given any D subset of [ A] 2, we can associate to it a set C by setting C = { ( b, c) ∣ { b, c } ∈ D }.
