In coding theory and information theory, a Z-channel ( binary asymmetric channel) is a communications channel used to model the behaviour of some data storage systems.

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.
