Abstract
In this work, we study the arbitrarily varying
broadcast channel (AVBC), when state information is available
at the transmitter in a causal manner. We establish inner and
outer bounds on both the random code capacity region and
the deterministic code capacity region with degraded message
sets. The capacity region is then determined for a class of
channels satisfying a condition on the mutual informations
between the strategy variables and the channel outputs. As an
example, we consider the arbitrarily varying binary symmetric
broadcast channel with correlated noises. We show cases where
the condition holds, hence the capacity region is determined, and
other cases where there is a gap between the bounds.
