Abstract
Embodiments are disclosed for joint communication and sensing (JCAS) applications with user equipment (UE) including collision alert detection, user vital signs detection, active autofocus in low-light conditions for camera applications and infrared spectroscopy to detect and identify components of a sample of material. Also disclosed is the use of an apodization range-velocity map to improve detection of targets.
