An AVC perspective on correlated jamming

The correlated jamming channel is one in which the encoder uses a Gaussian codebook and the interference in the channel is generated by a jammer who can input noise which is correlated with the transmitted codeword. In this paper we look at this problem from the perspective of arbitrarily varying channels (AVCs), in which additive interference is controlled by a jammer. The jammer in our Gaussian AVC variant is allowed to base its interference based on a noisy version of the entire transmitted codeword. Under randomized coding, we find the capacity of this model. Our formula specializes to recover other results on coding for the Gaussian AVC.
