Fundamental MMSE-Rate Performance Limits of Integrated Sensing and Communication Systems

A variational and Blahut-Arimoto-type framework that computes the exact MMSE-Rate Pareto performance limit of ISAC systems while retaining the ISAC signal's randomness, giving optimality conditions on the input and output distributions, a provably convergent iterative algorithm, and closed-form sensing-communication-optimal waveforms.
