Process and device for estimating the speed of movement of a mobile terminal of a wireless communication system

Image Number 2 for United States Patent #7254369.

Estimating the speed of movement of a mobile terminal includes estimating the impulse response of the transmission channel at a given instant, and estimating the time derivative of the estimated impulse response. Estimating the speed also includes determining of a ratio of the energy of the estimated impulse response to the energy of the estimated time derivative.
