There is growing interest in human tracking, human activity recognition (HAR), and person identification by reusing wireless signals transmitted by existing communication devices, such as WiFi and cellular radio transceivers.
Radiofrequency sensing systems have emerged as viable alternatives to cameras for environmental monitoring.
In particular, a well-established method for detecting and classifying human movements using reflected radio signals is the timefrequency analysis of the small-scale Doppler effect, termed micro-Doppler (mD) caused by different parts of the body, which requires
sampling density and regularly spaced channel impulse response (CIR).
The proposed method addresses the problem of enabling integrated sensing and communication in realistic communication systems, reusing existing communication traffic for sensing as much as possible and thus introducing only a minimal amount of additional overhead.

  • Bluetooth channel protection for Android devices

    This patent describes a security system for Android devices that can block access to Bluetooth channels by unauthorized, potentially malicious, applications. This patented invention is a novel solution for the protection of Bluetooth and Bluetooth Low Energy channels in Android[...]

  • Countermeasure against relay attacks

    In the context of Vehicle To Grid, various cyber attacks can target electric vehicles as well as their charging station. The present invention solves the security problem related to the EVExchange attack and, in general, to all relay-type attacks: it[...]

  • A method for self-calibration of mmWave radar networks from moving target trajectories

    The proposed technique computes the roto-translation parameters of multiple mmWave radar devices respect to a reference coordinate system. The method calibrates radars in pairs and it is based on computing the optimal rigid transformation that matches the movement trajectories of[...]
