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 Sign in to download full-size image FIGURE 6. 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 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, … 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.
