Abstract
The paper considers an information-theoretic bi static integrated sensing and communication (ISAC) model and provides new results on the fundamental limits of this model. Specifically, we show a strong converse result for memoryless ISAC where the channel transition law depends on an underlying binary hypothesis, which the radar receiver wishes to determine with largest exponential decay rates of the probabilities of detection error under the two hypotheses. In this sense, the channel is a compound channel, and we establish a strong converse under maximum probability of error criteria. We further prove that the fundamental limits of our ISAC system remain unchanged under average probability of error criteria as long as the admissible channel decoding errors are bounded by 1/2.
