channel can model include a telephone or radio communication line or cell division, from which the daughter cells contain DNA information from their parent cell. This channel is often used by theorists because it is one of the simplest noisy channels to analyze. Many problems in communication theory can be reduced to a BSC. Conversely, being able to transmit effectively over the BSC can give rise to solutions for more complicated channels. See also Z channel Notes References G. David Forney. Concatenated Codes.
