Webapproaches for this problem, and each of them has multiple variants. Before describing these asymmetric coding techniques, let us quickly review how to solve the problem in the symmetric scenario. A. Symmetric Channel Coding: A Review Let W be a symmetric binary-input, discrete memoryless channel (B-DMC) and denote by C(W) its capacity. The binary symmetric channel can model a disk drive used for memory storage: the channel input represents a bit being written to the disk and the output corresponds to the bit later being read. Error could arise from the magnetization flipping, background noise or the writing head making an error. Other objects which the binary symmetric channel can model include a telephone or radio communication line or cell division, from which the daughter cells contain DNA information from t…

WebLet X n be a memoryless uniform Bernoulli source and Y n be the output of it through a binary symmetric channel. Courtade and Kumar conjectured that the Boolean function f : { 0 , 1 } n → { 0 , 1 } that maximizes the mutual information I ( f ( X n ) ; Y n ) is a dictator function, i.e., f ( x n ) = x i for some i.
