Binary symmetric channel problems
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). For results on general binary channels we refer to [5]. Note that while ... WebThe binary symmetric channel (BSC) with crossover probability p, shown in Fig. 6, models a simple channel with a binary input and a binary output which generally conveys its …

WebThe channel capacity theorem also holds for continuous valued channels, which are very important in a number of practical scenarios, e.g., in wireless communication. But before studying such channels, we need to extend notions like entropy and mutual information … Webare permutations of each other, then the channel is called symmetric. For such a channel, we have that H(YjX= x) = cis constant for all x2Xand so H(YjX) = cas well, and so for any …

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. We propose a clustering problem, which is … pork chops with beer gravyThe 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… sharpening a fingernail spindle gougehttp://web.mit.edu/6.441/spring05/reading/Forney_ExpEBBSC.pdf pork chops with apricot jamWeb3.
