A BSC is de ned by the PMF: P YjX(yjx) = (p y6= x 1 p y= x: … 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 … See more 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 … See more Shannon's noisy-channel coding theorem gives a result about the rate of information that can be transmitted through a communication … See more • Z channel 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 the binary entropy function, … 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

WebJan 18, 2024 · In order to fully characterize the equivalent binary symmetric channel, that prior knowledge ($P(y t)$) should be taken into account, which improves over $n$, i.e., … WebMay 10, 2016 · I want to send one bit x over a noisy channel, specifically, a binary symmetric channel with error probability p, where p = ( 1 − ϵ) / 2 and ϵ is small. In other words, the error probability is close to 1/2, so the capacity of the channel is small. The obvious method is to use a repetition code: repeat x many times.
WebA binary symmetric channel (Example 7.13) has an error probability Pe. The probability of transmitting 1 is Q. If the receiver detects an incoming digit as 1, what is the probability …
WebThe analog of the binary symmetric channel in which some bits are lost (rather than corrupted) is the binary erasure channel. In this channel, a fraction α of the bits are erased. The receiver knows which bits have been erased. The binary erasure channel has two inputs and three outputs as shown in Fig. 5.
