Opportunistic Joint Sensing And Communications
Abstract：
In communications-enabled sensing, of particular interest in the millimeter Waves (mmWave) bandwidth - wherein radar and communications tend to be similar in both channel characteristics and signal processing - a radar receive chain is co-located with a communications transmitter, possibly sharing information, and suitably processes the backscattered signals in order to undertake short-range sensing of the environment.

Conversely, radar-enabled communications rely on ambient backscattering, produced by low-complexity and nearly zero-consumption devices, in order to sustain communication links: among the enabling factors for these architectures we find the recently developed technology of Reconfigurable Intelligent Surfaces (RIS), which are low-consumption, intelligent mirrors capable of redirecting astray rays towards a desired point.

The talk reviews some recent results concerning these two complementary paradigms, both inspired by the Integrated Sensing and Communications (ISAC) philosophy.
