Integrated Sensing and Communications: A Tutorial on Mathematical Foundations, Signal Processing and System Design for 6G

Integrated sensing and communications (ISAC) is a cornerstone of sixth-generation (6G) wireless networks: a single waveform, aperture, and hardware platform simultaneously conveys information and senses the physical environment. Its literature, however, is spread across radar signal processing, estimation and informati...
