The arbitrarily varying channel (AVC) models a channel with unknown parameters that change with time in an arbitrary way from one symbol transmission to the next. The relationship between the error probability suffered on the AVC by a deterministic code with random block interleaving and the error probability predicted by an unknown, fixed channel model (i.e. a compound channel) is investigated. The main results are that codes of this form can achieve the same error exponents as fully random codes. Optimal codes (those achieving the exponent) can be designed by choosing codes appropriate for the associated compound channel
