Binary symmetric channel problems

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… WebOct 16, 2013 · Fundamentals of Probability Theory (4/12): Binary Symmetric Channel. http://adampanagos.org This example defines and investigates a communication channel …

WebProblem 1 Encoder and decoder as part of the BSC channel: Consider a binary symmetric channel with crossover probability (P_error) 0.1. A possible coding scheme for this channel with two code words of length 3 is to encode message a1 as 000 and a2 as 111. With this coding scheme, we can consider the combination of Websimplify our analysis, we have restricted ourselves for the moment to binary discrete memoryless channels. For simplification of the exposition, in this paper we will exclusively focus on two special cases: the binary symmetric channel (BSC) and the Z-channel (ZC).
