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) . The symmetric capacity is the highest rate … 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:

Let A i be the event that bit i is sent through the channel, i = { 0, 1 } , B i be the event that bit i is received by the channel, i = { 0, 1 } b) Find the probability that the input was 0 given that the output is 1.
WebMar 29, 2024 · While the problem in your code seems to be a duplicate as kazemakase points out in a comment, your code should not use such a loop and a Python list in the first place. With numpy one usually tries to push as many loops as possible into the numpy data types.. import numpy as np def main(): np.random.seed(4) in_name = 'in_img.png' … 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.
