WebSep 5, 2012 · The binary erasure channel (BEC) is perhaps the simplest non-trivial channel model imaginable. It was introduced by Elias as a toy example in 1954. The emergence of the Internet promoted the erasure channel into the class of “real-world” channels. Indeed, erasure channels can be used to model data networks, where packets … WebMay 11, 2024 · 1 Answer. If the Hamming distance between x and y is k then there are k positions at which x and y are different. If x is given and we would like to see y at the output then we would like to see k changes and n − k non-changes. Assuming that the channel works independently of the input and independently of its own history then the probability ...
WebA binary symmetric channel has the following transition probabilities. P(0) = P(1) = 0.5; P(0'0) = 0.8 a. Make a channel diagram showing the transition probabilities. 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…

Web3. The Z channel. The Z-channel has binary input and output alphabets and transition probabilities p(y x) given by the following matrix: Q = 1 0 1/2 1/2 x,y ∈ {0,1} Find the capacity of the Z-channel and the maximizing input probabil-ity distribution. Solution: The Z channel. First we express I(X;Y), the mutual information between the input
