High Quality Content by WIKIPEDIA articles! An arbitrarily varying channel (AVC) is a communication channel model used in coding theory, and was first introduced by Blackwell, Breiman, and Thomasian. This particular channel has unknown parameters that can change over time and these changes may not have a uniform pattern during the transmission of a codeword. uses of this channel can be described using a stochastic matrix , where is the input alphabet, is the output alphabet, and is the probability over a given set of states , that the transmitted input is equal to the received output . The state in set can vary arbitrarily at each time unit . This channel was developed as an alternative to Shannon's Binary Symmetric Channel (BSC), where the entire nature of the channel is known, to be more realistic to actual network channel situations.
