    Abstract: Systems and methods for determining fine grain motions and vibrations of live and/or inanimate objects are described based on using a radar system. For example, biometric information may be extracted from such vibrations associated with a live object. In different embodiments, processing circuitry may perform different statistical analysis on reflections from the objects. Moreover, the processing circuitry may perform different processing functions based on the statistical analysis to determine the vibrations with high accuracy. Furthermore, the processing circuitry may also select one or multiple target maps based on a field of view of the radar system for a more robust measurement of the vibrations associated with one or multiple objects.

    Abstract: This disclosure relates to methods for low latency orthogonal frequency division multiple access communication, according to some embodiments. A wireless device may determine to communicate with another wireless device on a frequency channel as a pair of wireless devices. The wireless device may coordinate with a set of wireless device pairs to share medium access on the frequency channel. The wireless device communicate with the paired wireless device on the frequency channel in a frequency division multiplexing configuration with the set of wireless device pairs.
