Webthe same holds for all columns. We say that such a channel is symmetric. Symmetric channel may be alternatively speci ed e.g. in the form Y = X + Z mod c; where Z is some … WebThe channel is represented by a stochastic matrix whose rows are labelled by the elements of X (input letters) and columns by the elements of Y (output letters). By definition ∑ y2Y W(yjx) = 1 for any x 2 X: Examples. 1. Z-channel (called so because its diagram resembles the letter Z). W = (1" "0 1) 2. Binary symmetric channel (BSC(p) ) W ...
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 input faithfully, but with probability p flips the input. Formally, the BSC has input and output alphabets χ = = {0,1} and. FIGURE 6. WebThe binary symmetric channel (BSC) has the input alphabet X= f0;1g, the output alphabet Y= f0;1gand the transition probabilities input 0: P YjX(1j0) = 1 P YjX(0j0) = (1.2) input 1: P
Web二进制删除信道（Binary Erasure Channel）又被称为二进制擦除信道，BEC是二元通道，即它只能传输一个符号（通常称为0和1）。（一个非二进制信道将能够传输两个以上 … A binary symmetric channel (or BSCp) is a common communications channel model used in coding theory and information theory. In this model, a transmitter wishes to send a bit (a zero or a one), and the receiver will receive a bit. The bit will be "flipped" with a "crossover probability" of p, and otherwise is received … See more The channel capacity of the binary symmetric channel, in bits, is: $${\displaystyle \ C_{\text{BSC}}=1-\operatorname {H} _{\text{b}}(p),}$$ where $${\displaystyle \operatorname {H} _{\text{b}}(p)}$$ is … See more Very recently, a lot of work has been done and is also being done to design explicit error-correcting codes to achieve the capacities of … See more • Z channel See more Shannon's noisy-channel coding theorem gives a result about the rate of information that can be transmitted through a communication channel with arbitrarily low error. We study the particular case of $${\displaystyle {\text{BSC}}_{p}}$$.
