Joint Communication and Signal Reconstructions over Multi-user Channels


Joint communication and signal estimation is important in several communication systems employing hybrid analog-digital radios. The goal here is to reconstruct an analog signal with reasonable fidelity, while simultaneously conveying a digital data stream. Several interesting multi-user information theoretic models with message and state communication are considered in this talk, for which optimal communication and distortion trade-offs are investigated. We further explore multi-terminal coordination problems, where the objective is to simulate joint probability distributions across distributed terminals, using rate limited links.
