 systems and applications.
The course will begin from first principles and ramp up to real-world systems and technologies. Keywords
 related to this course includes: GPS, drones, motion tracking, localization, data analytics, acoustics, IMU sensors, mobile security, data
 analytics, signal processing, pattern recognition, etc.

    - Foundations
                                    (linear algebra refresher, signal processing from scratch, probability refresher ...)
    - Mobile sensors                          (GPS, IMU, microphone, camera, vibration motor, RF (WiFi, BLE, UWB, Cellular))
    - GPS and indoor Localization     (trilateration, triangulation, differential GPS, SLAM, AoA estimation, dead reckoning ...)
    - Motion tracking                              (3D orientation, HMMs, Kalman filtering, inference, clustering, walking analytics, sports analytics, ...)
    - Gesture recognition                        (clock synchronization, Doppler, FMCW, Correlation, ...)
    - Pattern recognition                     (DTW, finger tracking, smart toys, ...)
    - Sensor security and privacy        (side channels, non-linearity, classification, cross-domain attacks, ...)
