Lecture 2.1 Information Theory of ISAC: Rate-Distortion Tradeoff in ISAC by Prof. Giuseppe Caire

Описание: Integrated Sensing and Communication (ISAC) is a paradigm for which a communication system is endowed with sensing functionalities beyond its communication functions. As sensing and communication share common transmission resources, in terms of bandwidth, power, and hardware, a basic question is what is the optimal tradeoff between achievable communication rate and sensing performance, which can be defined as some form of distortion (or error) incurred by the sensing function (where this may be target detection, target parameter estimation, or more in general the RF-imaging of a desired field of view). Significant recent research has been dedicated to answering this question in an information-theoretic sense, considering different models and sensing distortion functions.
This serves to quantify the potential advantage of new ISAC schemes that fully integrate sensing and communication, with respect to “conventional” schemes that partition the transmission resource and the hardware between the two functions. Also, often the information theoretic analysis of the problem suggests interesting achievable strategies, which in turns provide guidelines on principled system design. In this talk, we review these recent results and point out that, while some models have been solved in a nice and satisfactory way, there are still many interesting open problems that need to be addressed.
