Abstract: Integrated Sensing and Communications (ISAC) is one of the new features of future wireless networks (in short, 6G). The scope and variety of scenarios in ISAC is vast, with many possible ways to formulate problem and tools to address them. In this talk, I shall review some of these problem formulations and approaches spanning information theory, statistical signal processing & communication theory, and deep learning. Some recent results in information theory show that, in certain idealized scenarios, the fundamental tradeoff between communication and estimation can be characterized exactly or approximately. This characterization reveals certain fundamental aspects of ISAC system design. Then, I will consider the problem of radar parameter estimation in monostatic and multistatic systems using communication waveforms (notably, OFDM and OTFS) instead of traditional radar waveforms. Finally, for the case of the estimation of extended targets, I will show how the problem formulated in terms of classical maximum likelihood detection and parameter estimation may be ill-posed, while schemes based on deep learning can yield very attractive results.
