Novel approach of acceleration estimation via time-frequency image of GPS carrier signal

This paper proposes a novel approach of acceleration estimation via Time-Frequency image of GPS carrier signal, and the Time-Frequency images are generated by the Wigner-Ville distribution. In TF image, the time-frequency uncertainty is restricted around instantaneous frequency curve in a few number of TF image pixels. Hence by reasonable parameter configuration, the acceleration estimation precision is almost unaffected by the dynamics stress, and the acceleration estimation can achieve high estimation accuracy, and takes place of the function of accelerometers in some conditions.
